I've had this problem more than a few times now, and am wondering if it's common?

Every couple of years, I recall traumatic events that occurred in my childhood. I've told my parents 5 different times about sexual abuse - first time was one day after (I was 5 y.o.). According to my parents, we spoke extensively about the event. No recollection.

Eleven or 12 years later, I told them again of the first and later molestation. One year later, brought it up again. No memory of talking about it before. A couple years later, I did it again. Now, age 38, it's happened again!

How do I know that I won't forget it again? I can understand forgetting the first time ~ I was so young ~ but 3 more times?? It's not as though I've been entirely happy in those years of not talking about my past. Rather not. I stuffed it inside and every time I'd get that memory triggered, I freaked out & acted up in some way. It's really depressing to look back and see so much of my life has been chaos. I don't want my life to continue like this...it sucks!
