all my friends are leaving me behind

my friends are all good at sports and i can’t even walk. my friends are good at academics and i can’t understand basic concepts. all my friends are good at singing and music and all the other arts, and i can’t do any of it good enough to be enjoyable. i try so hard to be like them and every time i do i fall behind. it’s always been this way, i’ve never been good at anything, i will never be good at anything. whenever i try i feel like a little kid playing vanilla wow at level 70. i’m so jealous of all my friends that are going to have a future. i know i’ll never be a failure but i’ll never be anything more than mediocre.
