Bitch at work- venting

I am a waitress at a bar tonight I started work at 5 along with three other waitresses one waitress was “sick” had to leave so it was us three. I am 15 weeks pregnant I have been diagnosed with hyperemisis. I honestly throw up anytime I drink/eat so I went to the bathroom and puked at least 5-6 times tonight on top of that I have gallstones which severely kick in after I’m on my feet for to long so about 3 hours in I can’t even stand anymore and I have to leave every single person I work with is understanding because obviously I’ve had drs notes and it’s out of my control then one girl comes up to me and starts yelling at me because I kept “running to the bathroom” umm what else was I supposed to do puke on everyone? Ugh sorry just needed to vent
