Paperback book. Anxiety is a survival skill gone haywire. It happens when our brain is working so hard to protect us that it forgets to notice that the danger has passed. It feels like choking, stifling, smothering, tingling, panicking—our brains cut out and we start to make bad decisions—all normal anxiety reactions. Dr. Faith G. Harper, author of the bestselling Unfuck Your Brain and This is Your Brain on Depression packs a ton of knowledge and help into this practical manual.
