Victim of something illegal

(Sexual abuse warning if triggering please don’t continue and I hope you are doing well and better)

I was a victim of a child predator and child pornography. I unfortunately lost all his contact information so I can’t trace him down. If I went to the police I slept with a man at 17 who was 18, he will be innocently charged as well when they search my phone. Even if I had a way to catch him, I couldn’t without arresting someone I was friends with. I just wanted to open up since I told my mom for the first time yesterday I’m 19 In a week and half and I was 14-15 when this happened and he was 30. I was reaching out wondering if anyone wanted to be friends and we can help each other when struggling with anything since I wish I need a friend rn. Idk what to do. I can’t get him without remembering my old insta that’s been deleted and my Kik I don’t use.
