Run...as fast and as far as you can. Women's refuge, anything, this is the kind of emotional abuse a that leaves real lasting damage over time.
At least with a beating you can see what is hurt and treat it. This...does just as much damage and is much harder to treat.
I doubt you have any of the disorders he has made during his armchair diagnosis. It also wouldn't matter if you had them all, he has ZERO right to treat you as he has.

I can't begin to list what is wrong with what's going on, but it session he groomed you into being his current victim. The fact the abuse started so soon after you arrived. It sounds very similar to cult behaviour. Rapidly cutting you off your family, then bombarding you with negative imagery about your lifestyle/personality that you have developed because of contact with the outside world, etcetera etcetera, so on and so forth.
Then then they want to break you down to rebuild you.
Only they don't, they break you so your too weak and exhausted to argue, or protect yourself.

I truly hope you find the strength and belief to break free.
Good luck.
