Hello and welcome to PC,
I also considered myself a strong person, but I finally realized that I needed help. I fell to rock bottom before I gave in, so my climb back up has been a long one. I'm truly sorry for what happened to you. I hope you give in as I did and seek some help. I'm afraid that your past is effecting you worse than you realize. Repressing your feelings may be a short term solution but it isn't a long term one. My advice to you is to seek some help. What can it hurt? I can assure you that what happened when you were a child was not your fault. God Bless You and I hope you find peace. Lots of helpful people on this website who have been right where you are.

Best Wishes, Cajun
