Don't hesitate on what you want to show to others. If you know that there's a lot of potential on yourself, then show them that you're not weak. Show them that you're strong, you're brave and more. Don't show them on what they think about you, show them on what you think about yourself, on what you can do. If you have lack of confidence, don't rush yourself for the reason that you'll just end up like that again. Just gather all your confidence slowly. Make yourself comfortable. Don't think about negativity about yourself especially some rumors they talk about you. They will be ashamed on their actions if you show to them that you are not weak. Only yourself know something about you. That's the more important thing, manage to know yourself.
