That's great to hear you have already tried but discouraging your mom wants to argue instead of take turns and listen. Is there someone else in your family you and you mother are close to who could be there at the same time to serve as a mediator / peacekeeper?

Actually I have a sister who is a psych professional. She told me that our mom may have some sort of personality disorder that is why I am having a hard time to make peace with her. I tried but I think there's a part of her that feels guilt as well and at the same time, her anger towards me is at a maximum state that she cannot forgive me anymore.

I hope your sister's training and wisdom offer you some comfort. As you said, you tried...
