I work part time at a large stadium doing security for about 6 months now.

Often times I'm working in the lines to get in alongside somebody, checking bags and doing the metal detector etc. Overall it's been a fine job until recently I was having flare ups at work where I needed to go to the bathroom, and then my boss would freak out because the line would shut down because they didn't have enough people work. I tried explaining I wasn't feeling well and they weren't very sympathetic to my concerns, saying I should've gone prior to my shift.

The whole situation made going to work extremely anxiety inducing, before my couple shifts after that I would be nauseous and feel like I gotta go to the bathroom. Just a really dehabilitating state where I was terrified I'd have to go, and thinking I have go but getting wrapped up in my head and feeling terrible to the point I get chills and feel like I might vomit.

I got COVID which gave me a week off which was a blessing in disguise, but I start back up tomorrow and I almost want to quit, but scared how that will look for future job prospects, this is by no means is a career, I have a college degree, I just was trying to save up to move but I don't need this job, however quitting might look bad.

Does anyone have any advice how to deal with these issues while on the clock at work?
