Zero Support Today As A Cashier

I have good work days, I have bad work days, which are rare, however, today was the worst shift of my entire life.. so today I was working from 1-7:30, and it was all chaotic during the afternoon (mainly because of the snowbirds, I think, which is understandable), however, the closing cashier called out, and I decided to volunteer to stay till close (despite my 30 minute break from 5 to 5:30), however, I immediately regretted that decision because:

• there was a very slow bagger with me throughout my shift until 8 (after that, I was on my own)

• The store was going through a very deep clean overnight & everyone was moving stuff around, not even bothering to ask if I needed help. Plus I felt like there are cliques in the store. They all just left me on my own with a bunch of impatient customers

I tried to keep my composure, but unfortunately, the anxiety & pressure made my performance consequently slip & lost total focus. I’m my own biggest critic & I felt disgusted with my performance tonight.

As I’m writing right now, I have to go in at 10 am tomorrow, and I can’t even sleep because I’m not happy about tonight… I’m worried it may affect me tomorrow and I do not want that. Without giving me harsh feedback, because I’m in no mood for toxic replies tonight, what’s the best advice you should give me going forward tomorrow??
