" People throw that word around -- anxiety -- like it's the same thing as running late for a hair appointment or receiving a bill you're not sure you can afford. But if you get a bill you can't pay, then yeah, you're going to have some anxiety, but that's justified. It's normal. But real anxiety, disordered anxiety ... it's a different animal. It's irrational, and knowing it's irrational doesn't make it better -- it just makes you feel like you're crazy. "
