I could really use some encouragement or words of support right now. Two days ago I started a job as a dishwasher for a very busy restaurant. I was anxious and nauseous all day before going which means I was hardly able to eat anything before going. Got to work, did most of the day, but ended up vomiting in the bathroom. I didnt tell my manager because my dumb anxiety brain kept telling me not to be a burden. So I kept working until I nearly passed out, at which point my manager saw me and sent me home. 
Now I'm terrified to go back in today. Super nauseous, shaking with anxiety, but I know I need to go to work because I need to pay rent and loans. 
I dont know what to do, any help or advice is greatly appreciated.
