I think your parents and other 'adult' people made you responsible for their feelings, I know they did because I read a lot of your stories. My dad did that too. And that's so wrong! Because later on you still believe you are responsible for what other people are going through. At least that's what happened to me.
But you 'must' blame your mother for disliking you! You were a child, she was an adult, she chose to have you! You didn't chose her.
