trying to hang in there,I think I need more help?

I'm hesitant to post cause I don't have much experience and do not know what to expect.I don't have enough people to talk to.I'm bi-polar but have been stuck in a depression for almost 3 years.My wife has been depressed for more than 30 years.I thought I could help her when we first met over 30 years ago but even with the better med's we have today she spends most of her day in bed.I've been put on welbrutin and it seems to be helping. I also started cognitive behavior therapy but everything is so hard . I feel that if I get going I'm somehow deserting my wife. I really need some encouragement. I was supposed to start a peer tutoring class today but I could'nt make it.please help me. Larry
