Fake friends

Do you know what hurts the most?
More than the pain my ex put me through?
When you were crying, everybody left
when you needed someone, everybody left
except of me
I kept caring, I gave everything I had
why? just to make you happy again
and now that you're fine, I need someone to take care of me
everybody left too, that's not a surprise, that's just how people are
But the only difference, the only surprise is
you, my 'best' friend went with them all
