I had a similar scenario a while back, was only a part time till tart... I had a major panic induced IBS episode at work one day (undiagnosed at the time), doing evening shift, manager had gone home, only me and 2 other staff there. Had to run to the loo 3 times within half an hour, each time being asked if I was ok and giving the generic 'yeah, fine' as you do lol but eventually had to ask to go home, with much embarrassment as they could all guess why! Anyway, next time I went into work got a grilling from the deputy manager for leaving just two staff and not producing a doctors note! It wasn't my fault they didn't have enough staff to start with, and I'm not sure how I'm supposed to get a doctors note for having the s*its at 9pm on my way home... That situation triggered several more of the same until I couldn't even get to work without a problem... :(
Thing is, I really hated it, was my first ever job and it caused so much anxiety I was really struggling to do it, but I didn't once complain about it or have to tell everyone about it every day (unlike some of my colleagues at the time!). I think most people have 'issues' they keep to themselves and struggle on, it's just a shame some other people assume you're ok as long as you don't have limbs hanging off and just think you're a lazy !Removed!.
