My cousin is going through similar feelings regarding her abusive druggie crazy religious parents. She's working on not allowing them to dictate her value. Their opinion and thoughts have no control over her worth. Whether they are apologetic or not is not her problem. Her problem is to look herself in the mirror and tell herself it doesn't matter what happened to her, it doesn't matter what they've said, she carries no scarlet letter, she is awesome, intelligent, beautiful, caring, loving, she is all the things they were not and therefore on a whole separate level that they can never touch upon. She needs no one to validate her feelings. She needs no one to validate her trauma. She doesn't want to make room in her life for people unworthy of her company. She has no room in her life for those who cannot take responsibility. She controls her day, each day. She controls her validity. She controls her worth. Maybe these thoughts can help you.
