(((MamboQueen))) - I know the sad feeling, but I also know how much better I felt when I realized it was out of my hands.
I've BEEN the homeless A, and I've LOVED the homeless A. The "loving" part was the hardest, as I was no longer numbing myself, but I'd finally accepted that I could no longer step in and "fix it" for him. Sounds like you are at that point, too.
Gentle hugs and prayers,
Amy
