Abusive Partner Who is PG Lead

I'm a stub year and want to leave big law already. The main partner I work for, who is also the PG lead, yelled at me for an hour over something that was not even an issue.

Not working with this partner is not an option. I don't know what to do at this point. I'm the most miserable I've ever been in my life. I don't want to do this job, I know it's not for me. Period. I get anxiety about the next day at 4PM. I'm crying everyday. I get Sunday scaries on Saturday.

But I also know the job market sucks and I have no idea what I would even do if I quit. I'm just completely lost.
