Coworkers 😤

So I work at a hospital in a pharmacy and Im almost 8 months pregnant. I walk on average 5 miles a day and dont get to sit hardly at all. Today I had about 7 or 8 of our largest bins full of medications to deliver plus 3 smaller ones. My coworker had about 4 or 5 bins half the size of the ones I had to use. I had to do 2 runs of patient specific medications on top of everything else during the morning. I also had to cover 2 other coworkers job while they had to go to a meeting. Then I had to pull 200ish medications to fill our 75+ ORs and then return a bunch of medications. I forgot to do one of the patient specific runs. My coworker flipped shit on me and threw a fit(literally was throwing her arms around and stomping). I took a 20 minute lunch and got 1 10 minute break because my supervisor asked what was going on when she freaked out and I told him I hadnt even sat down once besides my lunch. Im supposed to have a 30 min lunch and 2 15 min breaks. I also clocked in 30 minutes early. I have now hit 10 hours and just finished everything I needed to get done. My shift is supposed to be 10 hours. I can feel my feet swelling and they have never hurt this bad in my life(they werent even this bad in basic training). Just wish my coworker could make it a team effort instead of watching me drown in my work while 8 months pregnant. Keep having braxton hicks all day too. Also on day 6 of 12 of working in a row. I want to curl up and cry. Over today.
