I was sitting in the staff room when I saw my supervisor. She asked me if I done the front. I said the back but I was confused. She said "oh for goodness sake" in an annoyed tone. She went out. Then came back in and told me to hover the front and clean the windows. She also said "it's not fair on the others". Why the other staff? When she said that, I felt really bad. I went out and I cleaned. While I was cleaning, I felt so sad. I had suicidal thoughts and the bad thoughts again. I hovered the front and cleaned the windows. And plus, I overworked. It nearly time to go too when she told me about this. I finished and I went back into the staff room and I tried to find her. I asked someone but they didn't know. The supervisor wasn't there. She went off I guess. My supervisor does swear in front of the staff and is angry often. I'm worried, I don't want to lose my job. I can't help it if I'm a retard. I forgot to do it. It's my mistake. I'm not perfect. I do try my best.
