Missing piece

Please, let me go...
Don't keep me waiting...
I'm so tired...
Sick and tired of this...
I've had it...
I want to achieve my goal,
You're not my goal,
I'm not your goal,
So, why am I wasting my time?
You've already realized it, for sure.
Why am I being so stupid?!
I'm stronger than this,
I know I can do it.
I'm off now...
Going to find that missing piece,
For my puzzle,
Wich is my life...
We all live for something,
I've just still haven't found out
What it is...
But I will,
Believe me.
I won't give up...
