Personality Disorder

Hello it's me,
the laughing fool
the crying heart
the bleeding tool

Hello it's me
but I don't know
who I am
if not for show

If I'm sad
I don't know why
If I'm happy
I could cry

Hello, hello,
please don't call me
I have no name,
no face to see

I am not
but still: I am
and I struggle
to comprehend

What part of "me"
is "me", is pure
which of this "me"
am I for sure

Hello it's me
the hearty tool
the laughing cry
the bleeding fool.
