I'm really depressed

TW:Self-Harm I really felt like I was doing better. I messed up tonight. The ROCD thoughts became so overwhelming. I couldn’t stand it , I was breaking down. I was having thoughts of SH myself just to make the thoughts stop. I gave in and the thoughts did stop. But I feel so empty. I feel like I failed. I relapsed after years of being clean from SH. I don’t want my girlfriend to know and I feel so much shame. I don’t even know why I’m posting this here.

My life has been hell, and I don’t know how to move on. I (15M) did awful things when I started high school, thinking being sexual was the way to connect. I crossed boundaries, overshared, and kept flirting with friends and making sexual jokes, even after they said no (all over text). One friend stopped talking to me and can’t even look at me now. I feel like a monster. Why shouldn’t I be locked up? If I got therapy, I feel like I’d be sent jail. How can I ever move on?Then there were these 2 guys who were older than me one was 16 one was 17. The 16 yr old was introduced to me by my online friend who is my best friend and I begged the 16 yr old for pics (idk how it started but after my friends ex randomly messaged me and sent me pictures and then blocked me right after I think I became addicted to chasing that high) the 16 yr old eventually sent me a pic but it was real and I stopped bugging him on it after that but i feel so bad I did that but my friend tells me not to feel bad cause the guy was weird but I still feel bad. Then the 17 yr old I did the same thing with him but went too far when I tried getting pics from him by using my best friends ass pics she sent me (she was 15) I don’t think I grasped how wrong this was but that’s not an excuse she eventually found it when I told her after she tried getting pics from the guy herself to try and help me and the guy got mad when she stopped talking to him cause we found it weird talking to him. I told her about how I sent the pics she said she felt sick but forgave me cause she thought I was gonna harm myself. Fast forward the guy told me after I had still been flirting with him that I s@d him (we never met in person ever) and I felt so guilty and apologized a lot and he got annoyed and told me that he had been kinda manipulative to me and kept me in a loop of mystery and I don’t talk to him anymore. But one of my other friends stopped talking to me after I was being by too emotionally taxing on him because I became very depressed and didn’t wanna life anymore and tried to stop lifing a few times. And now idk if I actually s@d someone if I did that to someone and now I think I’m a pdo and I think I s@d my baby cousins and my little brother and now I’m scared bf I can’t even get help because my parents don’t believe in therapy and even if I wanted to I’m scared because I don’t want to go to jail but I think I deserve it honestly why should a monster like me live.

I have sent nudes before when I was younger and I am really struggling with the fact that I have sent them because it makes me feel like I am such a bad person and I don’t deserve certain things. I try my hardest to be a good person and do the right things but I obviously have made lots and lots of mistakes. I cannot get over these mistakes I’ve made because I judge myself so hard for them and it’s making it hard to function.
