The last song i want to hear here

This started off so well but things just fall apart
I came with innocence and left without a heart

I know you said you cared
Tonight I'm gone
Goodbye

I'm sitting on the floor, I'm feeling really sick
I won't turn on the lights, it's better in the dark

I wish I could stay here
If I did then I'd cry and disappear

I'm never coming back, I'm never coming back
I'm never coming back, I'm never coming back
I'm strong enough to leave and never turn around
All that I'm leaving here is all that I'm not now

You'll stay, I'll leave and you'll smile
I'll grow as I go and leave this all behind

I wave goodbye but not say goodbye
I've said all that I want to say
