Esthersvirtue,
Sorry you are hurting.

If I recall you had said you are "avoidant personality" too? Well,in this post here, you said " I just want to stand face to face with her and say ...why????"
Don't know about you- but letting someone know how I REALLY feel is a challenge for me. Do you think it might help telling your mom how you're feeling? Perhaps she doesn't realize how her actions are affecting you.. just a thought.
Wishing you and your brother well.
Mandy
