My fault?

I'm guessing this is my fault
your gone and i cant stand it

living life with out my best friend
is just killing me and making me restless

every last second is amounting to all the last moments

sadly its hard living life now but the worst part is i cant show it,

try pretending to be happy to fool others into thinking your Kay

when honestly the new life style sucks
and that last thing you wanna do is make him pay

I'm guessing this was my fault
for doing things to cause are fights

when the honest truth was it was all a test
and you proved all the negatives right

i wonder if you cared
and you proved me wrong
I'm done , farewell and so long
