I've been MIA the past month cus I've been working. I am a hair stylist and work for great clips. Everything has been literally going great until today. My boss asked me last week if I could help out another salon because they are short on people. I agreed to help and today was the day I worked at that salon.. Its half the size of mine, and a man came in and I had seen him at my salon before. He is rude, grabby, and a drunk. I immediately remembered him from before and I panicked. My anxiety got the best of me. I stepped away and called my boss and told her I was freaking out. She completely understood it and told me it was ok. I was able to leave with no problems or bad looks from anyone. Which is a good thing but I've been feeling like this all day now and I still can't shake this feeling...
