These past four days have been the worst performance-wise I have ever been since I started working here 8 months ago. One day a card doesn't go through at window and the car runs off without me getting to ask them to pay properly. That same day I accidentally handed off the wrong food items at window to a regular. Another day I'm doing DTO and, because I didn't queue drinks properly for the window person, the wrong drink gets handed out at window. Today, I find out the cold brew I made yesterday had too much water and so it spilled all over the floor (I cleaned it up ofc) AND I forgot to take out the grinds afterwards (albeit because I was distracted trying to do front/CS tasks while cleaning up my mess). Today I also accidentally bumped heads with another coworker and my glasses got bent, so I couldn't see properly for the rest of the shift and probably misread some labels while I was on bar :(

There were a bunch of other small mishaps that I cannot name at the top of my head but I am just so frustrated with myself. I thought I would be doing better since I was done my semester and therefore wouldn't be high strung from school, but now I'm high strung over simple tasks at work??? One of my shifts even noticed and pointed out I'd been tense this past week and told me to take the next few days to stay home and relax. Am I just burnt out?? Am I a bad partner???? I don't want to be someone my coworkers can't rely on and with my line of back to back mistakes recently I feel like nobody would ever want to work with me ever again :( What should I do to prevent something like this from happening again?
