help please

I’ve never been the type of person to open up about myself but these last 3 months have been the hardest, worst time of my life. I’m 16 years old, and I’ve been anxious and had anxiety my whole life. Over the last couple years I’ve learned how to cope with my anxiety and be a happy person. But one night in January, i was watching random videos on YouTube, and a video about serial killers came on. I’ve always been interested in crime shows/documentaries, so I didn’t think twice before deciding to click on it. In the middle of the video I had this intrusive thought that said “why do people murder loved ones or innocent people” and “what does it feel like to kill somebody” I am not aggressive, or have ever caused harm, but these thoughts scared me to death. I felt a instant shock of anxiety and panic immediately. I thought something was wrong with me. I turned my phone off and went to bed hoping the next day I would forget about it. Unfortunately I never forgot about the thoughts, and still have intrusive thoughts that affect my day to day life. I feel so hopeless, even after seeing a therapist, and being on Prozac for 5 weeks I don’t feel a difference. Every time I try to be positive and tell myself “they’re just thoughts” ocd tells me, “yeah sure, but what if you did these things”? “What if you WANT to do these things”? I stress that I might actually want to do these horrible things secretly and am convinced that one day I will commit these crimes. I don’t know what to do anymore, I feel so hopeless, and even being around my girlfriend who used to bring me so much joy, I still can’t be my regular self. Please I feel so hopeless and sad I can’t even do the things I used to enjoy, remembering I have these thoughts is with me 24/7 from the second I wake up to the second I fall asleep. Anybody have advice? Sorry for the rant I just needed to get this off my chest. I just want to be normal again and enjoy being around my family and my girlfriend again

Hi. I’m just really scared and I want to ask questions. I have been ocd and have been really suffering since December. The intrusive thoughts come like I want them now and it’s more of a “ well oh yeah you want to do that, and it’s gonna happen” and I start panicking and can’t focus and it scares the shit out of me. Is that ocd? Or is there something wrong with my brain and I’m actually some psychopath you see in a movie? I’m terrified. Im scared to be around my family, I’m scared to be around everyone. But I’m scared to be alone as well because I’m alone with the thoughts. What if these aren’t intrusive thoughts and I’m actually some terrible person who’s gonna hurt someone or is actually some psychopath who’s crazy? I hate this so much because I use to be so happy and not have any of these intrusive thoughts or worried that I was going to to hurt someone and now I’m so scared all the time. Can someone please answer some of these questions? I just want to make sure that this is ocd and I’m not a terrible person.

Ive had intrusive thoughts for 2 months now..And I just remember about serial killers and now I imagine myself doing those things to my family and I feel uncomfortable looking at them. And now im questioning if I like my thoughts or not and it’s just causing me more worry I’m even googling my symptoms but nothing is show up. I also get sexual intrusive thoughts about the serial killers and it’s horrible and scary someone please help me.
