What am I?

I've been within a endless battle for years. Yet every day I hide the marks with a smile.

I'm not perfect, even at times I try to be.

I change fast to fit in with my surroundings.

I've changed so many times I don't even know my true colors.

I often question myself, even when I know im right.

I like people who I know will break my heart.

I trust too easy.

I crave the sense of having friends, yet  diss my real ones.

I cry, I bleed, I breathe, I am only human
