This guy has issues, but I still love him

So my bf and I have been dating for almost a year. We're both older, in our forties. In the beginning we hit it off really good. One concern I had about him was his medical and emotional problems. He has migraines, sleep apnea, OCD, weight issues, and the worst is his depression. I not only accepted him the way he was, I wanted to help him with these issues.
After a few months his anger started coming out. He would fly off the handle with the slightest thing. We got to the point that we couldn't talk to each other without him screaming and ultimately it ending in a fight. He no longer was this sweet guy but I still loved him. The anger is getting worse as the months go by.
Should I stay with him?
