I just got finished laying in the tub under a luke-warm shower ejecting food out both ends of my digestive system after soiling myself trying to get in my car and drive to work after being up all night with similar issues. And I'm laying there crying because I know I'm letting the other employees down and that this will probably be a write up and maybe cost me my job.
(Said issues very specifically caused by a nasty TV dinner that was my meal after a 13 hr shift, no worries of underlying health problems.)
TLDR: I'm violently sick but years of employment have conditioned me to feel like the real problem is me not going to work.
