This kinda has something to do with SGP

First I was afraid
I was petrified
Kept thinking I could never live
without you by my side
But I spent so many nights
thinking how you did me wrong
I grew strong
I learned how to carry on
and so you're back
from outer space
I just walked in to find you here
with that sad look upon your face
I should have changed my stupid lock
I should have made you leave your key
If I had known for just one second
you'd be back to bother me

Go on now go walk out the door
just turn around now
'cause you're not welcome anymore
weren't you the one who tried to hurt me with goodbye
you think I'd crumble
you think I'd lay down and die
Oh no, not I
I will survive
as long as i know how to love
I know I will stay alive
I've got all my life to live
I've got all my love to give
and I'll survive
I will survive
