Why does it hurt so much?

What do you do
if you don't know wrong from right
what do you do
if you cant tell darkness from light
what do you do if you learn to hate
what do you do
when you forget to appreciate
what happens
to those that don't stick around
what happens
when you stop hearing sound
what happens
when no one seems to care
what happens
when you need someone there
where do you go
when you cant take the pain
where do you go
when you feel heartbreak over an over again
where do you go
when no one picks up the phone
where do you go
if no one even cares if you come home
why does each day get harder to go on
why does it feel like no one would even care if i was gone
why does this life hurt so much
