Is it normal for OCD/anxiety to cause harmful intrusive thoughts and overthinking?

HARM OCD MY LONG STORY. I wanted to post my story just incase someone else can relate to my intrusive thoughts. I’m am 16 years old and I suffer with anxiety but lately I’ve had intrusive thoughts to do with harming myself and others on and off for about a year now but they are really bad at the moment. I remember I had my first set of intrusive thoughts when I was around 11. I was on Instagram ( I know you are not supposed to have it till you’re 13 but all my friends had it at 11 so I felt like I had to haha ) I remember I read a post about someone commiting suicide and I quickly googled to check what that meant as I didn’t know and as an 11 year old that freaked me out as I had never thought about suicide before and I thought to myself “that’s awful what if that happened to me and I wanted to kill myself” I remember this thought scared me and I thought that just by thinking that maybe I did want to and I remember I kept getting thoughts that said “I wanna kill myself” in my head and they scared me so much so I told my mum and she told me these thoughts were just triggered by a scary post and I quickly forgot about them. It first started around a year ago when I was on summer break from school and when I was at my friends house and we was watching a documentary on YouTube about a serial killer as my friends and I found them quite interesting. I remember suddenly as I was watching it I got a random thought “what if I became crazy and wanted to kill everyone”. I remember my heart skipped a bit and this thought terrified me as I had never thought about anything like this before and I thought “Oh my god no you’d never want to do that” and I quickly forgot about it as I was with my friends and I got distracted. The next day I continued that documentary at home by myself as we didn’t completely finish it and they thought returned “what If I wanted to become a serial killer” and again I was completely terrified. I was terrified that this thought meant something and I kept asking myself why do you keep thinking about that and I couldn’t get it out my head. I then kept thinking about this thought for about a week and I kept wondering why I was so obsessed and kept thinking about it. I remember thinking to myself “what if you are thinking about it so much because deep down you actually want to do it?” I remember this made me burst into tears because I’ve have always been such a caring and kind person and I’d never want to hurt anyone I can’t even hurt a spider if it’s in my house I have to remove it careful lol! After obsessing over these thoughts for about a week I returned back to school where I got completely distracted and didn’t have these thoughts for about 4 months! I then remember getting a scary thought again 4 months later when I was watching the news with my mum, dad & brother and on the news was the story about I think terrorist attack in London where someone had stabbed a couple of people and I remember watching it thinking “oh my god this is awful, I can’t believe things like this happen” etc. I then remember a random thought popped into my head and it was “what if that happened to me and I went crazy I went round and stabbed people” I remember this thought made me cry and I had to leave the room and my family and I went up to my room and I started crying and I thought to myself “why the hell would you think of that” and I kept telling myself “it’s just a thought you know you’d never do that” and the thought actually passed and I didn’t think of it again. I then didn’t have any harm intrusive thoughts until now. I hadn’t had bad obsessive thoughts for about 5 months since now. About a month ago I watched a video called “reacting to the scariest 999 calls” and I really wish I hadn’t but it didn’t even enter my head that this could trigger my intrusive thoughts. One of the calls in the YouTube video was a serial killer who after every kill rang the police to tell them he couldn’t help it but he just kept killing people. This again absolutely terrified me and I straight away thought to myself “what if that happens to me and I can’t help myself and I just want to kill people” I straight away turnt off the video and my heart was beating so fast. I remember I straight away burst out crying and I just kept thinking to myself “what if that happened to me” and “what if I become a serial killer” and “what if I want to do that deep down but I don’t want to admit it”. That last thought was the one that triggered my anxiety the most because I believed that if I’m thinking this it just mean something and maybe I actually want to do it even though these are genuine fears and things i fear happening so much. The next day I woke up and straight away these thoughts popped into my head again and stayed through out the whole day and the whole next week. As the weeks past and I kept worrying and obsessing over these thoughts the worse and worse they got and I literally could not get them out of my head. After a week of worrying about becoming a serial killer my thoughts then moved on to another set of worries. As we are in a global pandemic and we are in quarantine I am quarantining with my mum, dad and brother I remember I got a thought “what if I just went downstairs and grabbed a knife and just stabbed all my family isn’t there stories of teenagers doing that? What if that happens to me and I do that” This thought made me feel so sick and I literally could not stop crying and again I started to obsess over it. I then started to feel weird when I picked up knives because I was having these horrible intrusive thoughts about stabbing family members that literally disgusted me. I also had thoughts about “what If I just took a knife out with me without even thinking and I stabbed random people when I was out.” I literally couldn’t touch knives for a week straight and if I didn’t I felt extreme anxiety because I had fear I was going to act out these thoughts and I just felt so so so scared I can’t explain. The more I worried and obsessed the worse they got and quickly. I remember I’d just be watching a video on YouTube of a random girl and I’d think “omg she is so pretty” and then out of nowhere my brain would go “I wanna kill her” and then I’d think “NO YOU DONT WHAT THE HELL AND WHY THE HELL ARE YOU THINKING THAT THATS HORRIBLE AND DISGUSTING”. I could also just be talking to my mum and having a normal conversation and my brain would go “I wanna kill her” out of nowhere which made me feel physically sick as I’d never want to do that and I love my mum and these thoughts honestly just made me cry straight away. I also had a fear I would just randomly snap and hurt someone so I worry that I’d argue with my mum and just out of nowhere lose control and hurt her. I argued with my mum over something and I got angry and I thought “what if I got angry and I hurt her” which made me so upset and then straight away again after that thought I got another random out of now where “I wanna hurt her” thought which just I don’t even know to explain but those are the intrusive thoughts that scare me the most. I then turnt to my dad as he is always so understanding and he knows I’ve always struggled with really bad anxiety. I opened up about these thoughts and worries and fears I was experiencing and he laughed at me. He said these thoughts were simply irritational and did not at all fit with who I am and my character. He reminded me that they were just triggered by the scary video I watched and that just because it happened to someone in a YouTube video does not mean it’ll happen to me. He said I also don’t have it in me to kill or hurt someone as I am caring and kind and that not to let these scary thoughts get to me. Opening up about seeking reassurance actually made these thoughts a lot worse and more obsessive. I thought by opening up about these thoughts I’d feel better and reassurance from my dad would help but it only helped for about 3 hours then the thoughts came straight back and they started to come back worse. I was out with my mum and there was police near by and I remember thinking “what I’m an awful person for having these thoughts and I need to go and confess them to the police so they lock me up.” and when I was out I remember thinking “what if I have a knife on me and I don’t know” and “what If I brought a knife out with me and I didnt realise and I just stabbed someone” and “what if I brought a knife out because I secretly want to do it” and I remember I started crying so much in public and I thought I needed to confess my scary and horrible thoughts to the police because I couldn’t be trusted and I’m an evil person. I then remember coming home and I just thought to myself “why do you keep thinking of such horrible things” and “do I actually want to do these things?” I also remember thinking “I must want to do these things if I’m even thinking about it” and I then got a rush of thoughts like “I wanna kill someone then I’m horrible person if I’m thinking this” and these thoughts kept telling me “I wanna kill someone” I then decided I couldn’t take any more so I contacted my therapist and told her all the thoughts I was having. She reminded me these thoughts were normal and it was just my brain getting all of my fears out. She said the more I think these thoughts mean something and that deep down they have a meaning or deep down I want to do them the worse and scarier they will get. She said to remind myself I can not control the first thing that pops into my head and when I get these scary thoughts I should write them down on a piece of paper then throw it away and just think these don’t meaning anything. She also said “Your wild imagination is normal its what enables us humans to be creative but sometimes this can be scary.” This calmed me down and I felt reassured as it was coming from my therapist. After talking to my therapist I started to feel better and everytime I had a thought I would just laugh write it down and bin it and remind myself they are normal and everyone gets them. But intrusive thoughts are like bullies so they came back worse and this time I could see myself doing these horrible thoughts in my head but I still tried to stay strong and reminded myself of what my therapist had told me. I then started googling these thoughts and it led me to intrusive thoughts and harm OCD which I literally relate to everything I have read online but of course I don’t want to self diagnose but I’ve already been diagnosed with anxiety and ocd comes under that. Dealing with these scary intrusive thoughts are so so hard. I will tell myself “I don’t want to do these things they just intrusive thoughts and my anxiety will make me worry that mean something but they don’t” but then my Anxiety and OCD will tell me “ maybe deep down I do want to do these things and I’m awful person” and “I want to kill someone these thoughts must mean something” I read online and my therapist has told that everyone has these thoughts but most people just don’t think they mean anything but no matter how hard I try I can’t help but think these thoughts mean something even though I’ve been told by my therapist my dad and online therapists that they don’t. I am so worried that deep down I want to act out these thoughts and that’s why I’m thinking about them. I’m so so worried that I’m a psychopath and a disgusting person and that I need to be locked up. As soon as I wake up I worry and it only goes away for a certain amount of time and these thoughts and worries come straight back. Please tell me there’s people out there that deal with this stuff too!! I’m here for you

Everyday i have unwanted thoughts and images in my head of me harming my loved ones in horrible ways, also urges too. i’m not like that at all, i don’t want to be like that at all and i also have an extreme fear of becoming a bad person and harming the people i love, or snapping out of anger and harming people. These thoughts scare me a lot and im really sad that i have these thoughts at all and its taking a toll on my mental health. whenever i see something like a gun or a knife or something like that i get anxious and scared at the thought that i could hurt someone with those things and i get thought about me in a position where i hurt someone. the last thing i want is to hurt anyone. i just wanna make people happy and i wanna treat others with kindness. i don’t want to do any of that i don’t wanna be a bad person. i hate these thoughts in my head and im so anxious at the thought that im gonna commit them. can someone help me and give me some advice on what to do?
