Who am I?

When I look at myself, I don't know who i am anymore.
The innocent kid that lived within me died when he closed the door.
Walking aimlessly through the world
Pushing away every single, loving girl.
Listen to the echoes of pain piercing through my brain
Listen to the sound of laughter that are one in the same.
See my cries, feel my shame.
Try to understand, then forget my name.
Listen to my words, answer my prayer.
Give me a reason why I should believe you care.
For years and years, I needed you
For years and years, I haven't heard from you
One last prayer, I need too try
I need to know, who am I?
