How can I cope with a bipolar, schitzophenic husband with border multipersonality disorder?

I love him but it is so hard to see him go through this. I am a Christian and don't beleive in giving up faith he will get better. We are moving to a different home this week and I aven't started packing yet. Next week I will be attending school for a position in my job that I can get a raise from. The following week I will be taking a major licensing test for work too. Among all of this, I work 40 hours and deal with kids, dinner, cleaning, and a disabled husband. My husband has major issues. He keeps saying he will hurt himself. He is a gun collecter too so it scares me. He can be so happy one minute but will snap for any reason. Last night he was happy and I just mentioned that I missed my favorate TV show. He blew up at me and yelled at me calling me horrible names in front of the kids. He said he hated me and wished I was dead. I sropped him off at home and me and the kids took off. We got home later on that night and he was still mad. He locked himself in our room and I slept on the couch. This morning he woke up as if nothing happened, happy again. Also yesterday he couldnt find a paper he needed and he broke furniture and made a huge mess for me to clean when I came home. I am tired of replacing phones, brooms, mops, etc just because he has a fit. I just got back into the church and am really hoping this helps me. I feel that my kids lives are being destroyed by his anger. Is there anyone out there with a similar situation? How do you cope? I am literaly getting sick. I have high blood pressure and suffer from post taumatic stress. I also have had severe dysplasia in the past. I am needing a biopsy for an abnormality in my cervix. Its just too much to handle. I feel alone.
