How do I maintain a strong sense of self-confidence after being bullied?

You just have to forget about it, it is past and probably won't happen again, it will also be really hard for you to forget but you have to stand on your own feet and be strong

Find cool and interesting hobbies that make you feel good about yourself and indulge on a regular basis. If it's immersive, it'll take your mind off the bullies. And if it's social or allows you to meet new people, then you'll have the opportunity to make new friends.

You have to keep in mind that you're not what they say about you. You know yourself better than anyone and they have no rights to talk about you or ofend you. Show them what you're made of. Show them you are strong and brave enough to stop listening to them. Show them you don't care about what they say anymore.

First, take the time to learn about yourself. Who are you? What do you like? Its so hard to forget those harsh words or even physical violence that has been done to us but have you thought of those who said good things about you? How many hugs have you had? Remember, each of us at some time has dealt with someone who has put us down or made us feel bad about ourselves but it up to us how we react! Love yourself and be proud of who you are! I guarantee you're a lot cooler than you think :)
