I'm sorry the two of you find yourselves in this most difficult situation. I can sympathize, somewhat, because I know my own mental health problems place a lot of stress on my wife that otherwise would not be there.

Unfortunately, I don't know what to suggest here other than for your husband to get some counseling or therapy of his own, if he's not already doing so. (Perhaps he is?) And beyond that some couples counseling, for the two of you, might be beneficial as well. It would also probably be valuable for your husband to have some time of his own away from home, perhaps with some friends, on a weekly basis so he has an ongoing opportunity to "recharge his batteries", so to speak.

Here's a link to an article, from PsychCentral's archives, on the subject of caring for a spouse or partner who has a mental illness. Perhaps some of the suggestions in this article can be of some help:
