Hi everyone, I'm struggling with what I think are intrusive thoughts, possibly related to OCD, and I'm hoping someone here might relate. When I was younger, in my early teens, I went through a period where I had a strong interest in pornography. During that time, I encountered hentai involving male characters, related to an anime I enjoyed. One of the characters was someone I even looked up to. I feel incredibly uncomfortable admitting this, but I believe I engaged in sexual activity related to it. Years later, I'm plagued by intrusive thoughts about this. I feel intense self-disgust and shame. It's like this memory has "tainted" my ability to enjoy that anime, and sometimes other things. I'm constantly replaying the situation in my mind, questioning my past actions, and worrying about what it means about me. The anxiety is significantly impacting my life. Does anyone else experience intrusive thoughts focused on past events, particularly those that cause feelings of shame or disgust? How do you cope with the constant replaying and questioning? I'm looking for support and understanding. Thank you for listening.

I know I shouldn’t and I’m trying not to ask for reassurance but how do I deal with this when I made real event mistakes in childhood? I’ve opened up to my cousin about this who’s an adult and believes that kids can be influenced at a young age and mimic things that they see and friends and my therapist. They all see the good in me and my stupid childhood mistakes but the guilt is very strong and even though I’ve opened up It’s telling me to open up more and more and I don’t know what else it wants from me.
