Because AL is so qualified to speak about anxiety disorders. Even if she does have an anxiety disorder, it's been years since she's seen a doctor for anything. If she did decide to break character, stop whining, and fix some of her self-inflicted problems instead of just seeking sympathy, her psychiatrist/psychologist would likely stress how important it is for her to actively push herself out of her comfort zone and do things that lightly aggravate her anxiety. No mental health professional would recommend using relatively mild mental illness (she's had a job, a "thriving" social life, and shares embarrassing details of her life to 30k+ strangers shamelessly, all while not treating her "anxiety disorder") as a crutch to avoid important aspects of life. No therapist or psychiatrist would just say, "Oh, okay then. You say driving gives you anxiety, so just don't. Avoid everything that makes you uncomfortable."
The "I have problems but I don't want solutions" look is not a good one, AL.
