How To tell my parents that I Have mental illnesses because I can't stand this anymore and I'm very very young. Any advices?

Hello everyone. I have been having horrible thoughts ever since I turned 13, and now I’m almost 16, and still having them. When I turned 13, the thoughts were constant and nearly drove me to kill myself. I thought about killing my family and pets constantly, but, worst of all, especially my mother. Now, I sleep with my door closed to try to stop the thoughts and to keep from hearing or seeing my mom or dad. I love my parents and pets, especially my mother— she’s an amazing woman, and has done so much for me, but yet I’m still having these damn thoughts. I was at a bad school when I was 13, and then moved to another when I was 14. After a switched schools, the thoughts gradually began to lessen, but every few months, they get really bad again for a few weeks (I still have them daily out of those bad few weeks, but when they get bad, they get bad.) I’m currently going through one of those spurts. I have tried to talk to my dad about getting help, and even though he said that he’ll look for a therapist, it’s been nearly a year, and I still haven’t gotten help. I desperately want these thoughts to stop because I feel like a horrible person and I love my parents, family, and pets so much, but I’m terrified of opening up to my dad and telling him everything that I think about (I also have thoughts about sexually abusing children, but I don’t want to do it! I’m not attracted to children whatsoever, but I’m still thinking about it.) My self-esteem is absolutely horrible, and I feel like a monster for thinking about these things. I’m very much a daddy’s girl, and if he is disgusted or angry at me, then I honestly don’t know how I’d handle it. I really, really need help, but just don’t know how to go about doing it (I’ve thought about going to the school councilor, but they’ve made it known that, if they’re concerned about a student, that they’ll either contact their parents or the police.) My dad has said to just calm down and relax, but I literally can’t. We have mental illnesses on my mom’s side, and many of those people take pills, and when I’ve talked to my dad about my anxiety and depression, he’s said that pills aren’t the answer. Honestly, at this point I don’t care what treatment I get— all I care about is these thoughts stopping. I’m sorry if this is rambling and a little confusing, but my mind is all over the place right now. Any suggestions would be very much appreciated.

I have a lot to say to my parents, I am 35 mine started young but hit hard at 16. Why didn’t they get me the help with this I needed growing up?? I could have been cured of this mess this disorder I didn’t have to suffer for 22 years. I feel like a fool like a idiot for suffering all these years I feel like a fool for my past for me trying to “figure myself out” it didn’t have to be like this or like it is for me right now my life could have been so much better and full of love. I am angry both my parents were drug addicts my mom had OCD she didn’t deserve to have kids when my symptoms got severe I turned suicidal my mom decided she wanted a divorce and abandoned us took my bro and sis and left me with her ex. I watched my dad tumble thru the divorce threatens suicide on me 3 times and I watched him put a shotgun in his mouth. All this is coming back up I am 35 now. I can’t stop thinking about the things I saw and the things that happened to me growing up. All this is on the surface now I am dealing with it. It’s all horrible I have been holding all this in for 22 years. I just want to be free and happy 😊. I feel Horrible

i'm sorry in advance for how long this post is and if it's to much information. i'm undiagnosed but have been struggling with compulsions and intrusive thoughts since i was 7 or 8. My worst intrusive thoughts theme has been about p*d*phil*s. I've been dealing with it since my freshman and sophomore year but these thoughts didn't become debilitating until June of last year. I had a panic attack and confessed to my parents about these intrusive thoughts. They were obviously shocked and share. I felt so ashamed and like a monster. After talking with my dad he said we would see a therapist about it. Sadly we never did the first appointment we were late and missed are spot and the second appointment i sprained my ankle the night before so instead i was in the hospital. After that i closed myself off i tried dealing with them on my own using sources like NOCD and stuff. I did try to bring up going to therapy to my parents. Every time they would ask me if the intrusive thoughts were back and I would lie saying "no i just would like to go to therapy" I was so scared they'd be afraid of me and stop loving me, especially my mom. Eventually after awhile my parents forgot about it and I tried ignoring these intrusive thoughts because I was so focused and stressed from school. I decided I could just wait till I turn 18 and schedule myself into therapy. recently though my intrusive thoughts have gotten worse. I recently had a convo with one of my friends who has intrusive thoughts as well and she's encouraging me to talk to my parents. I'm asking y'all what should I do. As much as I'm scared I want to get help because I'm sick of living and feeling like i'm day away from acting on my intrusive thoughts.
