Who am i ?

I cant remember who i am.
I cant remember seventh grade.
I cant remember fifth.
I cant remember fourth, third, second, or first.
The main years of my life that make me...ME.
Sixth grade was strange. I went from pink wearing normal girl to goth chick then i went through not really knowing what i am.
But now, i don't really know WHO i am.
how do i figure out who i am? Do i ask my friends what i was like during those years? What now?
This is so strange. This summer I've just been all over the place with my personality.
