I almost got fired and got really emotional at work. Now I feel mortified. What should I do?

I’ve been working as a waitress at a small cafe in new york for almost seven weeks. In the beginning, I had no experience, and was pretty bad. But for weeks now, I’ve been a perfect employee and a pretty excellent waitress. I don’t make mistakes. Or rather, I haven’t made a mistake in weeks. But today, I did; I brought out the wrong omelet for a customer and my boss got really angry. He said “You’re done,” and really meant it. He wouldn’t let me take any more tables for the day, and was fully planning on just firing me like that. I asked to speak to him and ended up crying uncontrollably. Big tears… with sobs.

I love everyone I work with and like my job, and I was so upset to have to leave everything. I have a four more weeks in the city, so it wouldn’t really make sense to try to get another job right now, and I do need the money. Amazingly, I got my job back with my usual shifts, but my boss says I’m on thin ice. I’m really scared to go back to work, and feel weak and silly. I want my job, but I’m wondering if it’s worth it (my boss can get on big power trips sometimes, ex. “everyone, if you don’t sell more than 5 specials tonight, YOU’RE FIRED!”) and also I’m worried about the reactions of my coworkers and how I should approach it.
