I work in retail, and I was asking some customers if they wanted to check out and they just ignored me and walked on. I don't know why this is getting to me so badly, but it is. If someone does not need your help, why can't they just say no instead of being rude and saying nothing? It pisses me off to no end. I've worked at the place for nearly 2 years, and this feels like the first time it has gotten to me to such an extent. I'm on anxiety medication as is, and I was doing well until this point. I've been told I fixate on the negative too much, and I feel I'm doing this right now but I can't seem to lift myself out of it. Any suggestions?
