And whoever it was that's been telling you you're worthless are either stupid or full of crap or both! NO ONE is worthless. We're all put on this planet for a purpose. Some of us may not know what it is exactly, but we do have a purpose.

Maybe you should go somewhere to clear your head. Maybe it'll help some. Get your thoughts in order.
