My husband has been out on comp for almost a year. He has a good job. His doctors say he is better but he?

seems to be milking it a bit now. True I don't know how he feels although he tells me every day that he feels terrible. It's hard to live with him since he seems clinically depressed more than anything else. I've encouraged him to seek help and he has been taking medication for depression. He is marginally improved. He either sleeps most of the day and/or wakes t.v. Sometimes he goes to the gym. I feel he doesn't help himself but understand that the struggle; lack of motivation due to depression. I do my best to avoid codependency scenarios but it's a struggle. This wasn't how I hoped my marriage would turn out. I pray for change. Any suggestions?
