it never ends

i've been stressing out lately about going to work. because it's summer. and we're busy. and i never know if it's going to be a good day or a bad day. and i won't know until i step in the door. this morning it was feeling like it was going to be one of the bad one's. i walked in. and no one was there. so i started working. checking off the list of things that needed to get done before we open. about 10 minutes into it. i'm still by myself. which is a problem. so i ask the boss if someone else is coming. and turns out, no. because the other worker took off, and the cover hasn't shown up. so i'm alone. which is awful. because there are still things that i don't know how to do. there isn't ever any time to teach me because usually there's only two of us and we both need to be doing something. so unless i come in on a day that i'm not working. i'm never going to get to learn these things. now that i know i'm by myself. i start freaking out. i'm rushing around trying to figure out how i can do as many things at once... i'm literally running for an hour and a half. nonstop. just going.... finally the cover shows up, finishes the last little pieces. and i don't know what to do with myself. i was so worked up. so stressed out. then it was all just. over. and i burst into tears. i just started crying. i couldn't stop it. so i ran to the bathroom, as fast as i could go. praying that no one noticed. i was leaning up against the wall with my hand over my mouth so that no one could hear me. just sobbing.
