Why do you believe in me?

I feel like giving up rightnow
more than you could ever guess
and how can you tell me not to
when you dont know whats for the best?

I know that you told me
everything will be okay
but your not a fortune-teller
what do you know anyway?

why do you always
push me to keep going?
I know you know I'm worthless
because its always showing

please stop lying to me though
cause everything wont be alright
I've already lost my will to try
I've already lost the will to fight

why do you believe in me?
I'm gonna let you down
I'm gonna disappoint you
do you like the way that sounds?

well I guess you must
if your still willing to try
but why do you believe in me?
can you just answer me that?....WHY?
