Things that come to mind

Prove Them Wrong (Please Read)

If you're being bullied ignore them
Because in the endgame
People like that don't mean I thing
If them call you stupid show them
How smart you are by
Graduating college
If they call you fat just become track captain to prove them wrong
If they call you worthless show them how much you're worth by making friends even if it's not a lot
And finally if they called you weak show them all your strength by continuing to smile right through all their taunts

Because in the end you will always be beautiful
And no one can ever change that
