"H, I'm really concerned about you and the possibility that you might be clinically depressed. I'm willing to go to the doctor with you and I'll sit in the waiting while you talk to the doctor" (a depressed person has no will to help themselves, so someone taking them by the hand can make a big difference).
Regarding R talk, maybe just say "Hey, it seems like you are going through a lot. Maybe we just need to take things one day at a time."
Definitely read or re-read the chapter on depression in DR.
Take care. I think that my H has been depressed for a long time, and he moved out after going through anxiety attacks about his life.
