My DM had severe depression when I was growing up. There was no money issues but I was neglected. She got better in my late teens but I left home for university.
One issue is that my mother refuses to talk about the neglect. If I ever bring anything up, she will get all teary and say that she didn't know or that it was not her fault that she was ill.
I went NC with her for about a year in my early 20s. She was miserable apparently. She would listen in when I called my dad. Eventually we started a relationship again. I just avoid to bring up the past issues.
I still hurt. 
People tell me to just move on... and I really try. However there are things which just bring up the past. I think maybe I need to speak to a psychologist to help me deal with the situation. How can I get the help I need?
