This is my friend not by choice

I have a friend
that is way different from others
the kind that sticks around, no doubt
not leaves your side and if
it may last a day or two.

This friend here is demanding
clingy and selfish,
it feels like a second skin, extremely itchy.

She does not want me to look pretty
will bring tears to my eyes,
my make up is ruined.
She is showing me that she is in charge.

Why do you socialize, they ask me
what they don't know is
this friend lives inside of me.
