I'm a person, just like whoever-you-are-reading-this.  I put my pants on one leg at a time, just like you [unless you're one of those crazy-talented people who can jump into their pants without ending up on the floor with a hurt back]  
I still haven't met that person, so you'd be the first!  Life's worth living and it's not worth giving up.  Whoever you are, don't forget that you're not worthless.  If anything, you're worth your weight in gold.  And if you don't believe it, than who will believe in you?  Have confidence. Be yourself.  Be authentic.  No one's opinions can define you.  It's all about perspective. Your perspective.
