Nothing's wrong with you and you're not crazy for feeling the way you do. I would go insane. Why are you with him and why don't you leave him? I don't know the backstory, but I imagine if he's sick that's why you're afraid to leave. But why put up with this kind of treatment and behavior? Sounds like no matter what you say or how you react it doesn't change. I wouldn't be able to deal with that for one second longer, myself.
