On top of being emotional, I woke up at 4am and couldn't go back to sleep and I ended up pulling something in my back 😩 I have only been at work for 45 minutes, training on the registers and now my neck and back are killing me. I got light headed and felt sick to my stomach while trying to finish my training. 😭 what else is going to go wrong today?!
