How did I get like this?

How did I end up hating myself so much?
How did I end up being so pathetic?
How did I end up being so hateful?
How did I end up hating my existence?
How did I end up wanting to end my life?
Plastering make up on everyday just so I can hide behind it.

I've gone through so much, and I'm not even 16 yet, that's the best thing. I just want to escape it all. Someone please rescue me from this, please.
