How...?

How can I be so cold
while walking through hell?
how can I laugh
when things are so unwell?

how can I mock you
grinning like that?
how can I smile
those feelings I lack?

how can I blame you
you didn't do a wrong...
how can I frame you
when it was me all along...

how can you still stand me
I lied and I lied...
how can you befriend me
when I was the reason you cried...

how can I be so cold
the cause of your hell...
how can I laugh
I'm the reason you fell...
