*hug* Please accept my condolences. I used to be afraid of joining groups, because eventually in any group someone dies, and it hurts so damned much to lose a friend.
Conversely, new friends add to the depth and breadth of life and make a life better... and that is what I focus on, now, when people pass and the world seems dim.
Here's hoping friends step in for all of the people who knew your friends and help you through... I've read your posts enough to know you deserve the best. 🙂
