Answer: Don't let other people's accomplishments bring you down. There special in there own way and so are you. Just because they did something cool it doesn't make them any better than you are. Maybe try complimenting yourself for things you do that make you feel accomplished. And if there is nothing that you do that makes you feel accomplished which I can only bet there is, do things that make you feel good about yourself. Also please don't feel like garbage, YOU ARE NOT.
