About a year ago, old memories of me molesting or coercing my younger sister to do sexual actions resurfaced. They had always been at the back of my mind, but I had not recognized their severity until recently.
This started happening when I was possibly eight and continued until I was almost 10 years old, and when she was 4-6. I don't know exactly what started this, or why, but I remember that I used to get her to take off her pants and let me touch her genitals in exchange for me playing with her. I would touch her repeatedly until she got highly uncomfortable or wanted to continue playing with me. While it never escalated past this, I did have the urge to have sex with her multiple times but knew that it was wrong, and also knew that what I was doing and the way I was touching her was also wrong. although we would play normally most of the time, anytime we were alone I would do this. She always looked uncomfortable, and sometimes even angry, sometimes I believe close to crying.
At about a year into this, I had slipped my hands in her pants when my mother was watching. She reprimanded me, and started yelling, but no other punishment. After this, I had barely touched her except for a few occasions that following year. One day, I decided to touch her again and the following week my mother confronted me about it, saying that my sister had told her that I had touched her. Both my mother and father were outraged and started screaming louder than I Have ever heard them. However, there was no punishment for my actions, although I did feel extremely guilty, which they were aware of.
Currently, I do not think she remembers my actions, and neither do my parents. I have been clinically depressed (and also have ADHD) since I was at least 7 or 8 years old, and currently my depression is at an all-time high since remembering (although my mental health was rapidly declining beforehand any way's). I think about it often and get sick at how much my parents still care for me, and how much my sister does as well. Recently I have also fallen to child pornography, and while I have not looked at it for a while, the thoughts and urge are still there, even though my anxiety peaks and my self loathing makes me feel nauseous afterward.
I am now trying to become a better person and trying to take life seriously in a hope that it may make me a better person and help my depression. I think that my first step should be apologizing and telling her the truth of what I had done and attempting to make amens for it. Sadly, I am a coward and cannot find the courage within myself to talk to her about it, and don't even know what I should say. Essentially, I am asking what I should do. What I should say and things to make this as right as possible, as I know it won't ever be something I can make up to her, but would still like to try.
