my friend , where did she go?

I sure could use my friend right now
It's her i can let my feelings free
I never cared too much
She always , always made me laugh
We loved making jokes
We loved not being part of the cool crowd
We had each other

I can't find the girl i knew
Change is growth
Growth is irreversible
Where is she?
Not here
She's part of the cool crowd now
It hurts like needles to lose her
