Every single day! I work full time so I basically have this anxiety constantly at the thought of going to work, the things I did to screw up at work, the thoughts my coworkers have of me, having to deal with my extremely extroverted and obnoxious boss, etc. I worry before I leave about the day ahead and then come home and ruminate about all of the "stupid" things I said, how I didn't take enough initiative, if I'm going to get fired...etc. My coworkers are ok but they're all extroverted people who love hanging out together after work and I just can't do that and I therefore isolate myself. I work in a centre for children with Autism and always have to work with not only the kids, but my coworkers as well. I never have a chance to escape to a quiet office or even my own cubicle.
My anxiety would be so much less if I could just work alone and actually have the time to sit quietly and make sure my work is done properly.
