The Compassionate Friends is a support group for bereaved parents and siblings.
Most cities have meetings once a month.
TCF has been a great help to my wife and me. There is something miraculous that happens when we share our stories with eachother. I remember how difficult it was to talk to my friends and family about my grief feelings. It was like they just didn't understand. Of course, they didn't really understand, because it had not ever happened to them.
