I feel tired, I got woke up through the night and then up at 5am for work. Work is retail so VERY busy today and had to stay back - I am usually a pretty relaxed/reliable/willing employee but I found myself getting more and more worn as the shift dragged on, plus I didn't get my full break which I was docked for, which is not a massive deal but rankled me. Also one of my colleagues was allowed to leave on time so it didn't feel fair.
I definitely was not the best version of myself today and that's putting it mildly.
