Dead On The Inside (A depressed Michelangelo story )

( COVER ART NOT MINE. And I've changed the theme of this story, hope that's okay)
Michelangelo, the happy go lucky turtle. He's known as the oddball of the family, always joking around, pranking anyone he can, and you can always find him playing video games or having a laugh with his brothers.
Its funny though, how one simple mistake can turn your entire world the other way round, and Mikey is the supposed king of mistakes. His brothers seem to resent him, make him feel like he doesn't belong. Nothing Mikey ever does is good enough, and he never shows it, all the hurtful words really affect him.
He shuts everyone out, and finds himself in a state he cant quite explain, after all, all he's ever known is happiness and the ray of sunshine that is never upset. But he is, and what would happen if, one day, he believes that he really isn't worth anything.
