Help and advice.

We've been living together for a few months, I knew he had ADHD and I thought that his victimistic and slightly childish attitude was due to his mother's upbringing (he had a bizarre childhood in many ways and to this day she treats him like a baby who can't be crossed). He hates me calling him out for things that in his mind, he's right. We had an argument, which only escalated, the guy literally broke several things in the house (from the door to the shower), took several tranquilizers, I tried to help him, he managed to get out with the car and crashed, the car was a total loss. (From then on, he went to the psychiatrist and was diagnosed as borderline, also due to his family history).

Since then, I have had many panic attacks, I am cold and distant, and he demands affection and affection from me, claiming that I have no reason to be this way, that now he will get better, since he is undergoing treatment. He doesn't think it has anything to do with my current situation, claiming that it's not for that matter, I'm undergoing psychiatric and psychological treatment, even my psychologist said that he's doing this to test me, that I'm being exaggerated in wanting to leave the house, that I can just ignore it. I think about leaving every day, but at the moment I don't have the means to leave, especially because I have animals and donating them wouldn't be an option. Today he came "joking" that if I cheated on him he would kill me, I started crying and he came to say that I'm very sensitive and that he would never do that, because he was already cheated on and never did anything against his ex. I feel extremely tired mentally, I'm very discouraged in general.
