While I don't think your sending her money is necessarily helping things, I know you mean well.
I have a friend who is socially isolated and has been gradually disappearing from my life. I know having more friends and company would do wonders for her, but I'm unable to be that person due to time and distance constraints.
It's hard, and painful, feeling responsible for someone who you know you're losing to substance abuse and mental health issues. I can't imagine how difficult it must be from the other person's perspective.
Thanks for sharing your experiences.
