The Happiness Trap by Russ Harris is a great book for people struggling with OCD, Social Anxiety, and/or general stress and worry. The author, Russ Harris, builds the case against our obsession with trying to feel “happy” at all times.
The aim of exposure therapy is to purposefully trigger anxiety so that the anxiety sufferer can practice feeling uncomfortable while not engaging in the usual rituals or escape strategies.
There are a whole lot of myths floating around out there when it comes to OCD. Even among mental health professionals, it tends to be a very poorly understood condition.
