Does this make me crazy?

Ok, so when you feel like an outsider,
Like your looking through a window at your own life,
Does that make you crazy?
Or does that make you completely sane?
How do I tell the difference between self-hate and actual pain?
I want to help others,
So that is my main purpose,
But when I try to think about my future,
Everything goes hazy,
I lose my self-worth.
I don't know what I'm against or what I'm for...
So please, if I offend you or I don't seem quite as nice as maybe I hope to be,
Please don't attack, or back me into a corner.
I know I may seem, crazy, deluded or scary,
But really, I'm just trying - Just trying
For my shot at happiness.
