What eats me inside

I lay thinking of you and the past
I see who was back there, who used to make me laugh
Who used to make me love
Then it dies off, a rose with no water
Nothings alright
Nothing lasts forever
I cant be perfect like you said
I was never perfect, I was never for you
You dont understand, you didnt lose it all
You didnt want it all to end
I lay there with tears running down, into my ears
I hear nothing only the rustle of my bed
