What kind of man tells his wife to go live in a homeless shelter?! Oh, That kind.
It occurred to me that when you mentioned the suddenness of this event, you also said he is diabetic, and not handling it well at all. His brain is being bathed in acid, destroying brain cells and it won't get better, ever. Your best option, especially since you are his favorite target, is to get out of the way of his vile behavior.
Yes, call a lawyer, find out what your rights are, do whatever they say to protect those rights and don't believe the venomous nonsense that spews out of his face.

I'm sorry you are going through this. Is it possible you can pack yourself up and go far, far away from this man? I know I am loathe to tell anyone about my problems in RL, you are probably the same, but...if nothing is holding you there, why not live somewhere You want to live? Perhaps this is the opportunity life has been waiting to hand you? A fresh start.

If your mom is gone, would your dad give you a leg up, your brother/sister? Perhaps they could help you, you could find work in their area, and a place of your own. You don't have to tell them all that's going on, but enough that they get the idea it would be good for you to start over, somewhere safe & Far away from this arsehole.

Best to you
