I work in a mall and it's packed on the weekends (of course) and whenever I walk I seem to notice people staring at me. Even in my store they seem to stare at me. I'm not sure what the staring is for but I do notice some do it intensely and it makes me nervous and I start to fidget with my hands or put my head down or twitch my mouth. I hate it and I'm trying to fix it. What can I do to work on that?
