I need some advice(perhaps legal, if there are any lawyers on this forum)?

I been in my current job a year. I have been laid off my previous job after the company started downsizing and my boss has been great and I really liked it. My current job is really a nightmare-it was misrepresented to me from the start-meaning I was hired to do one thing and then owner(this is a small business) wanted me to take over 10 other things that I would simply not have time to do. Noone trained me, no one showed me anything, its was extremely disorganized, none the less I learned how to do my job quite well I think(my coworkers say the same).

My boss is horrible-the biggest issue that he is verbally abusive and goes on rants on everyone all the time. Noone can please him with anything and no one does anything right. He declared numerous times how everyone is an "idiot" who works there. But there is also several times when he claimed that I was "acting like a bitch" and "all clients were saying it". Considering that most clients I talk to seem to love me and chit chat every time we speak, they wouldn't be doing it if I was "a bitch" as my boss says. He told me numerous times to "get the hell out of here and don't come back" and when I ask "are you firing me?", he would say"no, I am just upset!"

He constantly interferes in everything and simply doesn't let anyone to do anything without his "input"-I get emails from him at 10 pm how I "messed" something up(but so does everyone else).

This stress has really taken a toll on my health and I have been hit with debilitating migraines. so bad that I had to go to ER one time and they gave me shots. I actually thought I may have a brain tumor or something. I have great anxiety attacks now, every time I see email from him.

Why don't I leave? I have been looking for another job for several months now and so far nothing. Its not easy to look for a job when you have a full time job.

I am honestly past the point of caring about my current position and just wish he would fire me as he often threatens to do(he does that to othes as well). But its still hard not to get stressed out.

If I quit, I can't collect unemployment. I wonder if there is any legal recourse for me to take for "hostile work environment"? Or is there a clause for me to able to collect unemployment if I leave due to his verbally abusive behavior?

I tried to call Dep of Labor but lady said I don't have a case
