I agree with Big Mama here. As hard as those memories are now in time it often does eat at you if you don't find a way to address and overcome it, and for a lot of people talking about it is a great step. If you don't feel that you can talk about it could you write it down for yourself (through words, drawings, art - however you feel comfortable expressing the emotions) and then destroy the paper? Sometimes just the act of letting it out and then getting rid of it can help to ease some of the pain - it sounds strange but it does work. It can be confronting as it does force you to look at what you remember and the feelings behind it but most of the time it is so much better to let it out thsn try and bury it.

I really hope you can find a way to find some peace No-one deserves to have had to go through what you had to go through.
