I just want to send you big hugs too.

I can only imagine how sad this situation is for you. It is especially difficult to see kids go through this.
I think that one of the toughest things in life is loneliness. When I cut ties off from my abusive family, I knew it was the right thing to do but it left a big hole in my soul. I decided to replace them with loving, supportive people, and I have been lucky to find a few, including my DH and a few friends. This still didn't quite take the place of family, but now I have much more peace and happiness in my life. I hope you will find the same.
