On 7/4/25 I was up at 2 am watching tv. The show I was watching had themes of SA. I randomly got a memory of me committing COCSA. The memory was of me reaching out my foot while sitting on the couch to touch against the outside of my sisters thigh when she was walking by. At this time she would've been 17/18 (I know her being 18 wouldn't make her a child but since she was so close my brain thinks of it as COCSA). I got this memory and it freaked me out. Everyone I've told about it (Parents, pediatrician, and therapist) tells me that what I did was an extremely small thing, but the thought of me touching my sister for a sexual purpose without her consent disturbs me. I remembered questioning details of it, but not letting myself question them too much because I didn't want to absolve myself of guilt. On 7/6/25 I got the memory of this maybe just being an intrusive thought I had at the time. I didn't give this thought much attention because again I didn't want to absolve myself of guilt. On 7/8/25 I reached a point of being extremely suicidal and was heavily considering just killing myself. At that point I started questioning it more. I don't understand why I only started to remember this 3 years later. The next day I went to talk about it with my parents. They told me that they weren't sure of whether or not I did it and that my sister had never reported anything. They told me that I they would forgive me if I did. Later that day I was thinking about the memory. In the memory there was an bench acting as a footrest in front of the couch. She was walking between the bench and the couch and I put my feet back up on the couch to let her through and that was when I reached out. I remembered this happening back in 2022, but at that time the bench wasn't in there. This has made me seriously question the validity of the memory. Every time I'm almost able to move past it and tell myself that even if it is true I've changed and wouldn't ever do it now my brain goes back to telling me I'm a horrible person and always will be. I don't want to absolve myself of guilt if I actually did it. I want there to be some sort of consequence. I can't ask my sister about whether or not she remembers this happening because it could easily be mistaken for anytime I might have accidentally bumped into her. She seems like she's fine interacting with me, but I'm scared I might have left her with some sort of trauma. Thinking about whether or not it actually happened gets me nowhere and just results in my brain stuck for hours.
