Telling your therapist about a taboo event?

Hey guys I just wanted to talk about something I was feeling I feel so trapped and terrible I have a bad pornography addiction even back then idk what to do I'm 17 years old but basically I looked at some very obscure things on the Internet ranging from hentai or just even more messed up things when I was younger I think maybe early teens I remember randomly just started remembering things I saw now I do not remember if I acted on them or jerked off to them idk what to do I feel so ashamed trapped I feel like I can't enjoy life anymore for what I've done I been introduced to porn when I was young idk what to do I seem alot back then some memories pop certain ones I don't remember if I had pleasured myself to it it feels like I did I have so much shame if I did but idk what to do

This might be a bit disturbing but it’s been weighing on my mind. From all the posts I’ve made, I’ve talked about how I was influenced at a young age and saw things I shouldn’t have seen. A lot of it. I can’t remember much because it’s blurry and all muddy and in different timelines. Sometimes I genuinely don’t understand why I would do such a thing or how I could and I would constantly overanalyse things from the past. These things lead me to do things to myself out of trying to understand and curiosity and mimicking actions like kissing others in preschool. I made stupid mistakes I can’t take back and it weighs on me a lot. I don’t and can’t remember so much honestly but when I was at the age of 8, I inappropriately touched someone and it wasn’t out of harm but to understand why. What I did was wrong and the whole context of the situation is messed up but I knew to a certain degree it was wrong ( I spoke to this to my therapist who was very understanding and told me these things happen a lot when kids are young ) I remember at the time I felt guilt and realised I wanted to be a good person. I thought I was dammed for what I did and there was no coming back for me but I remember apologising to them and never doing it again. I had to keep this with me for so many years and it broke me a lot. I matured and realised my actions, spent time crying, thinking that maybe I shouldn’t be here, and was filled with a lot of shame and guilt with nobody to be there or know about this. I didn’t tell anyone because I was scared. I was scared to also be badly punished but eventually as time passed, the person passed away and nobody knew about the story. This year I began opening up and for the first time I opened up to people about this because I wasn’t doing good mentally and spent days—months ruminating, panicking, and thinking I was a monster for everything. I never thought I would but it was with people I trust who loved and accepted me. I told them the situation and how I felt. I told my therapist briefly and she told me we could continue this convo the next time and that I didn’t have to tell her everything but… It didn’t make sense to me. I felt like I needed to confess everything or else I was a fraud. I do definitely care about their justice ( justice overall ) for what happened to them regardless of them not being here and I’m beyond sorry that something like this happened to them because of my stupidity when I was younger. I try my best to be understanding and compassionate to myself but sometimes it’s all filled with hatred and shame and guilt but I’m trying. People say confessing makes things worst. I feel like this is something that needs to be confessed but Ive already admitted my actions, regrets and told others about this but yet it’s still there . I’m not an angel but I do know, these stupid past mistakes have made me more empathetic to people and not wanting things like this to happen to anyone. As I’ve grown I’ve realised how these things can distort your view of reality at a young age because now as I’m older, I understand so much more than my younger self would. Sometimes I don’t know what to say. I don’t know why I did certain things and people at my age were probably more matured and smarter than me. A lot of things happen in different timelines but I’ve matured so much and I understand my mistakes and the impact. I feel safe to talk about this to my therapist or here but to my family and others.. I don’t know what to say. I’ve made so many stupid mistakes and feel like I need to confess everything. I didn’t want to ever talk about this to anyone because I didn’t want to make things worst for people. This happened so many years back and I just didn’t want to bring the past into the present. I know that I have no right to really suggest this because that person was a victim. I don’t know what I should do. Confess? Or let it be in the past? I mean my therapist and close friends know about this.

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.
