What do you call it?

What do you call it
When you worry that your friends
Don’t like you?
Talk about you when
You’re not around?

What do you call it
When you feel you must
Be Perfect
In anything you do?

What do you call it
When any little mistake
Can make you burst into tears?

What do you call it
When you feel as if
You must know everything
Before you’re taught?

What do you call it
If you feel so horribly
Alone
When you’re surrounded by people you love?

What is it called?
Because I wish somebody would tell me.
