I know how he feels. I start a project like organizing pics, closets, legal papers etc. I do this so the family won't have to do this after I am gone
I am now on an anti-depressant celexa and it has helped. I still have to have projects to keep me busy, church act, a benevolence agency I work with weekly. Maybe there is something he can do. I write lots of cards to the ones who are ill in our church-etc. Is he a member of a VFW, Moose, Elks club?? They always need people to help with vol. projects.
I will pray for him and your family. He needs to feel needed.
Love Cindy
