Here is the deal I work at a juvenile detention center. I'm 5'7" and get a little nervous when I have to work with the larger populations. The younger males give me no issues as I typically out weigh them. In general I also tend to be a somewhat nervous person, I'm not sure why. As I've aged it hasn't been as much of an issue but I'm still aware of it. I want to be the person who can walk around thinking I am th shit and no one better F&^% with me, but not cocky just very confident. Any suggestions are greatly appreciated!!!
