Working long hours

Ch

I’m almost 27 weeks and and still working my regular shifts. Some are 10 hour days where it’s just me and 1 other person running the whole pharmacy. I’m bouncing between stations and trying to keep up but honestly my feet are so sore and swollen, my sciatic is flared up all the time and I’m exhausted. I can’t even have a long conversation with a patient without running out of breath. At what point did you cut back on work? I don’t want to lose hours but I really can’t do this anymore. I’m miserable 😖
