I am feeling mentally exhausted, but I am working really

I am feeling mentally exhausted, but I am working really hard. A few people irritated me today by doing whatever they wanted without considering how it affected my day. I’m completely sober, extremely tired, and having an uneasy day, but I'm staying busy and pushing through. I wish this weekend had been different, but it is what it is. I just want today to be over! I received my paycheck and enjoyed the rest of my day.
