A little annoyance can ruin the day, and self-doubt leads to endless rumination. Instead of letting these feelings pass, we analyze and process them in the hope that we will feel better. However, psychotherapist Gitta Jacob warns that this often has the opposite effect. Overthinking emotions like anger, fear, or doubt can amplify them or even create them in the first place. This book shows how we can effectively regulate our emotions: new scientific insights, practical exercises, and reflections help us regain control over our feelings and deal with our inner lives more calmly.
