I have no manner

I went to grab the food 5 minutes before they started. She told me and I said I was sorry. It was super embracing. I have no manner, I don’t know how to re-enter the society. I really in trouble. I am becoming a simp. The main problem is I am not working well, I feel I can hardly justify the money I get paid for the work, therefore I feel insecure and it messed up with everything. So the key thing here is: I need to work more, no need to get more done, just have to work first, I barely work anything these days.
