Ok, I had hard parents as well, and I have trouble with forgiveness. I just don't have it in me to forgive someone who treats me badly because of their own "problems."
I don't buy the "forgive and you will feel wonderful "etc,etc. Holding a grudge is not a "burden" for me, personally. It is very interesting I came across this thread because i am about to start a "mother" thread in relation to something I was reading online yesterday.
