I’m so sorry that you were so hurt. You certainly don’t deserve to be treated like this. Good for you looking for a new job. Some manager feel entitled to bully others a small percentage of that group had been bullied themselves and can’t hurt the person who hurt them. Almost all of those things he said to you there a chance that he is saying that to himself.

I would started scheduling yourself for self care days where you take care of herself mentally and physically. Take a hot bath, go for a walk, watch a movie you like, scream out your frustration in private. Just be sure to take care of yourself.
