<human>: Condense the text into a few key points

[20 F] Last semester, I missed a shift at my part time job. I woke up from a nap half an hour before my shift, with thoughts of just about everything awful happening in my life at the moment, and felt as if I were locked in bed. I left my dorm room and went to the bathroom, turned on the shower and sat beside the tub crying for two hours, and eventually made my way up to the top of my building. my boyfriend talked me down, but even after that, I started fearing that my boss would fire me for not showing up and not calling in sick for work.

The next day I scribbled out on a piece of paper that I had an anxiety disorder, and handed it to my manager.

To my surprise, she said "I need to know this information! I'm so sorry!" and for every shift after that I could hear her mumble to coworkers "go help her, she has an anxiety disorder and can't be left alone with a lot of people"

the fact is, I don't know when I'm going to freak out. I do know that it isn't to the point where I can't fulfill the duties of a food court cashier while I'm already on the job.
<bot>: Has anyone else gotten an oversensitive reaction, or worse, an insensitive reaction to their anxiety at work? How do I explain what I can and cannot handle without my boss challenging the legitimacy of my anxiety?
