What Am I?

I am someone fraught with self-belief,
And haunted by self-doubt.

I've got all the answers,
I've got nothing figured out.

I like to be myself,
I hate to be alone.

Sometimes I'm million colors,
Sometimes I'm black n white.

I'm up and I'm down,
But that's part of the thrill,
Part of the plan,
Part of all the things I am....

I'm an angel, I'm a devil,
I'm sometimes in between.

I'm as bad as it can get,
And good as it can be.

Sometimes I'm miserable,
Sometimes I'm pitiful.

I'm special, I'm beautiful,
I'm all extremes,
Try figure me out, you never can,
There's so many things I am......
