Who will I be

How can you replace me?
Am I to much for you to handle?
If so,
Then why did you have me?
Leaving me alone
This is so overwhelming,
For me
You can’t see these tears on my face?
You have no sympathy for mankind,
You only care for your self
I’m standing here try to know
Who I am!
I yell when I hear the story
Of these family that left me
I want it to break you!
You left me asking this question
Who will I be?
