dont know what to do.

I suffered sexual abuse when I was younger...but I have never told anyone about it...dont know if I should or how I should go about it if I did.I just want to get rid of those memories that are holding me back and just move on.. I think it is some of the reason I feel so worthless and dont fit in anywhere...I dont even fit in on these online groups...just want to stop the stupid psychosis......its my fault and i know that and im sorry for it,,,but i cant leave it in the past....
