Michah,
I am now 46 and for some reason everything I had stuffed down about my childhood started to come to the surface about a year prior to her death...I hear you when you say "if was that bad then I would remember"...but that isn't always true.
The human brain is an awesome thing and when you are a child with no one to protect you, I think sometimes the brain "hides" those memories until you are more able to deal with them...That is just my take on it...
Although in my experience....it has been very, very hard to find out that everything I believed for all of these years was just simply not true...That leaves you feeling like..well..I just don't know who I am....
Hugs to you Michah....It will come when you are ready for it to come.
