So I've had anxiety all my life. I just turned 22. I can't hold down a job for the life of me. I'll work somewhere for a few days, get overwhelmed, leave, try again. I worked at a GS Station for 3 days before I stopped show ok my up. Worked at Cumberland farms half a shift before I had a panic attack and left. Worked 1 day at Walmart, no call no showed there. Worked at Amazon a month, then left. Longest job I've had was UPS for 3 months. 
How do I get over this and actually work. I get so overwhelmed and worried while at work. I'm about to try Dunkin Donuts so... Any advice on working with really bad anxiety? Ty in advance.
