Help, husband has bunch of disorders

My husband has bipolar/manic depressive, phscytzo effective disorder, mood swings, and minor ocd and minor anxiety. I love him so much. Lately last few months he has been getting angry very easy over little things like me asking a question. I just don't know how to respond or what to do. He gets mad if I say anything and gets mad if I don't say anything. Just getting super stressed I don't even want to go to bed, I'd rather sleep on couch but then he gets mad bout that too.
