Hardest job I've ever worked

I just got home from work. It's 1:27, i got off roughly around 1.....
Day shift hasn't done even half of their duties all week, and night shift has had to pick up the slack, at the expence of our time. And Marina only had one fuctional leg today due to her surgery, and theresa decided that she only needed to schedule Marina and me to work....so closing took three freaking hours, mainly because we had 3 pans or more of meat to role that day shift didn't do, and we've been really really busy at night this week, tonight we had steady customers from 5 to 9..... I've never actually had this bad of a time closing before, the past two days has sucked.
I love this job, and the people I work with, they are all amazing and lovely, but this is getting to be a lot more than I may be able to handle. So those of you who are reading this, please please please pray for us all at Which Wich, and pray that I will have the strength to stick it out, and that Theresa (my manager) will have her heart softened by God, and that she wont judge our closing too harshly. Please Please pray.
