Yeah, I just don't think I have the patience. I'm a lot better about blowing up than I was in the past, I think thanks in big part to my meds... But for a while I was working booking appointments for insurance agents, and when people get huffy because they don't like that you called them, it started to get me after a while, and I could feel myself getting angry, stressed, and taking it personally. And the supervisors basically tell you that if you take the rejections personally, it is not the career for you. So I felt I had to look for work elsewhere.
And because of that experience, coupled with stories from retail workers online, I just don't think I can do it, the only possible exceptions being working in a music store, since I love music and I would hopefully be happy to go to work in the morning. If I work at some generic thing like Walmart or Target, a grocery store, or a department store, I'll have no reason to have a good mood ever, let alone if an ignorant customer gets under my skin.
