What I Lack

sleep won't come
I'm wide awake
I've got this feeling
I just can't shake
my mind's a blur
but the memory still there
I remember it all
is that so unfair?
I feel so lost tonight
with nowhere to go
somehow it's come to this
bringing me so low
I know I don't deserve it
I know I've made a mess
but if I got a second chance
I'd give it all my best
to giving it all up
so I could have it back
knowing it was worth it
for you are what I lack
