I'm an 18 year old, and just close to two months ago, I came to remember something I did when I was younger and since then I've been suffering, to varying degrees, from a great deal of shame and guilt.
Between the age of 12-14, I was sexually inappropriate with my sister, who was about 6-8 during the period. This went on intermittently, and varied in seriousness - sometimes I'd watch as she would get undressed, and at its most serious I let her use my finger to itch her private parts. I didn't do anything without her "consent", but given the circumstances (her young age and her developmental problems) I recognise that that doesn't really mean anything or change the nature of what happened.
I've told most of my family, and they took it in their stride, basically taking the position that it was in the past, and as it hasn't happened since they thought the best thing would be to see someone about it, which I did - a therapist I've been seeing for about a month now.
However, despite this I still feel awful about what I did. I recognise that it is natural to feel guilt after something like this, but I also feel the urge to tell the people I care about - extended family and friends - to let it out there and let fate take me where it will. However, at the same time I can't - my sister doesn't seem to remember what happened, and I don't want to run the risk of bringing it all up for her, as well as causing turmoil for the rest of my family, out of some selfish desire for catharsis and punishment. However, as it is I just feel disconnected from my friends+ext.family, unworthy of their love so long as they don't know the reality of what I did. I feel like I've gotten away with it scot-free.
There is one friend I've considered talking to about it, who I feel even in the worst-case scenario wouldn't spread it (my town is the sort of place where things spread fast and wide), but I don't know if telling her would even make me feel better or not - I think I might just be looking for something, anything to change how I'm feeling now, cos even with big things coming up (like Uni) I can't shake a horrible feeling that these feelings might not go away any time soon, and the though of being haunted by this for years on end is hellish.
Any advice and comment would be appreciated, thank you. It's so good to have somewhere to talk about this - I didn't think there existed anywhere on the net.
