Many of the most painful or troubling emotions we experience are reactions to events that have actually happened - but one powerful and sometimes paralyzing feeling can be provoked by things as yet to occur. Say hello to anxiety.

Psychotherapist and meditation teacher Andrea Wachter spent much of her life being stalked by the physical and mental manifestations of anxiety - the brain fog and the pit of the stomach dread of something bad looming on the horizon. She's amassed a wealth of strategies to overcome the thoughts and sensations that make up anxiety and she explains them to Dr Laurie Santos.
