Realizing my life is a mess.

There's something inside me you wouldn't understand,
Something that me myself can't understand,

You try to change but you always failed,
You promise you will always be by my side but you lied,
You always say nice words but you never prove it,
You lied again,

And the you is actually me,
How on earth you would understand me if me is actually a you?

This is how complicated my life is,
Somebody help me please as i really want to know who is you in me.
