I quit my job last night because I got threatened and I couldn't do it anymore.

There was a ton to get done and it was just me and my boss working. He wasn't helping and I had said I just wasn't sure how I'm supposed to accomplish it all before close. I was just thinking out loud trying to figure it out when my boss decided to yell at me. He said enough and that he can't take the negativity. He said I complain everytime I'm in [I don't] and that I won't be able to keep a job being how I am. I told him I didn't appreciate the threat and he then said he wants a positive environment. We went back and forth for a bit about that and I was trying not to cry. I don't do great in confrontation I tend to cry or buckle as is. Anyway I ended up telling him I can't do it anymore and I left.

My mental health is insanely bad as is and it won't improve there. I have no backup plan no potential job prospects so I probably really screwed myself especially because nobody wants a thing to do with me job wise. Honestly this is what spiraling and poor mental health looks like. If we are spiraling might as well fully commit I guess.
