Hello, meowmixx, and welcome to Psych Central! I think the main issue is what NOT to do--which is to try to cheer him up by saying things such as, "What do you have to be depressed about? You really have a great life." And trying to make him feel guilty, as in "You need to get up and do some things around here. Stop being lazy and feeling sorry for yourself!"

Maybe he will let you sit beside him and hold his hand. Make sure he gets to his appointments and takes his medication.
