Barb, I just lost one of my best girlfriends in July. Same thing. While I know SHE was angry and fed up, I know she didn't mean to do it. The stuff we have done is nasty. So many of us are lucky to be alive. My friend died when I was really going through some very rough stuff. It was her death that gave me all that more courage to keep fighting through all the BS. I know she wouldn't have wanted to see me go down where she went and I bet if she were alive today she'd be ultra proud and happy for me.
My heart and thoughts are with you.
