How why, when..

And dont you wish you will be okay?
you put me on my death bed,
said i should just go away
when your all thats running through my head

i just cant breathe without you here
and i feel the words i speak
create that one tear
that will run down your cheek

you promised to never to forget me
but you ruined it all
you made me blind so i couldnt see
and thats when i shall fall

i watched you walk away
watched you smile at the pain
you had nothing to say
which was such a shame,

now i feel all alone
wish i didnt think about you
but yet they expect me to move on
though i dont even know what to do
