McGinnis,
I am so sorry to hear of the abuse you suffered at the hands of your mother. I'm glad that you've made it to this site and have done some research on what is wrong with her. I feel the same way about my situation.
What a b*tch she is to say those things to you. I too have suffered from being overweight as a child and most of my adult life. My mother is the same way always acting like dealing with me was a hassle.
I know about turning that anger inwards and I'll tell you it is so unhealthy for you. It can lead to clinical depression and I myself have dealt with that. You have so much anger built up towards these people and we are trained to believe that they are revered, but they are not. They're evil and don't deserve to have the attention we give them, good or not.
I hope that you will find comfort amongst others that deal with similar problems and please keep your head up. Please lean on us and ask any question you may have.
