Most people are self concious about their appearance. Try going to the gym 3 days a week. After 6 months you will have more muscles and will have more confident about yourself. People will be less intimidating to you once you know that you're the tougher than them.How can i make myself more attractive, confident in public?
Take a page from Ru-Paul..';YOU BETTER WORK *****'; Go out there and act like your running ****!
Take some self therapy courses
Show them respect ,demand respect from them. and really listen to them when they speak to you. Body language is the best way to show self-confidence.
