As a general rule, I hate people who self-diagnose themselves with mental illnesses. But my friend says that she has anxiety, despite never having been diagnosed with it.

According to her, the reason she doesn't have a diagnosis is because her anxiety is preventing her from asking her parents if she can see a therapist. She says she has panic attacks and has difficulty talking to people, but from what I know she's just as anxious as a typical teenager.

She also refuses to talk in front of our class because of her anxiety. Everyone else hates talking in front of the class, but we all know that public speaking is an important skill to practice. Obviously, it really pisses me off when she talks over other students and our teacher. If she hates talking in front of people, why is she okay with doing that after being repeatedly told to stop?

Anyway, I'm not sure whether or not she has anxiety. The fact that she says she does without a diagnosis makes me really angry at her. Am I the asshole for being angry about this, and would I be the asshole if I told her that she should stop saying she has anxiety unless she gets diagnosed?
