I am who I am

I am my mom,
I am my best friend, who I knew since I was born.
I am my pen friend, who's traveling around the world.
I am my friends, because of everything we share.
I am as bad as everyone I know,
and as good as everyone I met.
I am who I am, thanks to the ones that put me down
and also thanks to the ones that picked me up.
I am the places I visited and the ones I'll visit soon.
I am my enemy, because of everything I do.
I am myself, because of everything I think.
I am who I am, because of everyone and anything.
