I’m 28, female and in the USA. I have struggled with (mostly undiagnosed) social anxiety my whole life. Except for a brief spell on antidepressants as a teenager, I haven’t been on medication for it in the past. 
I dropped out of college in 2016 due to anxiety and the fact that I was failing, but never have I ever not been able to hold a job due to it. It’s been hard but never debilitating until recently. 
For 12 years I’ve had jobs like Grocery cashier, gas station manager and recently—-hotel front desk clerk. The interactions with customers have always been very hard for me but lately have become unbearable. For about 6 months I haven’t been able to make eye contact with any customer and can barely make it through a transaction without feeling like I’m going to pass out from nerves. I feel like such an idiot at all times and if I make a mistake I think about it for days. From all jobs I’ve worked at I’ve gotten mostly positive feedback from managers and co workers but that does nothing to ease the anxiety. 
Recently I got a job as a hotel front desk clerk and when people got irate on the phone over things like rates, credit card procedures and the occasional question I couldn’t answer because I was new, I’d get so dizzy I’d have to go in the back with my head on my knees and try to get my heart rate under control. 
Fear of going to work got so bad that I ended up in the hospital on Saturday with chest pain. I fainted in the lobby. They diagnosed me with anxiety and sent me home with a 7 day scrip for vistaril. I called the hotel and quit. The mere thought of it made me sweat with anxiety. I knew if I went back I’d end up back in the hospital. 
So now I have this huge bill coming that I have to figure out how to pay because I have no insurance. I need an income for My regular bills too. I have no idea what to do. I. Need to find a job ASAP but how do I escape this happening again. I literally don’t know how to work with it. I’m so embarrassed and feel so worthless right now. I cant get any more medical help because I can’t afford it. What would you do?
