If you're wondering how to "ride the emotional roller coaster of difficult times" by building emotional resilience, you might enjoy listening to (or reading the transcript of) an interview with psychologist Marthinus Bekker that was aired on the May 17, 2020 episode of the radio program called Scholar's Circle. Here's where you can find it: http://www.armoudian.com/scholars-circle-building-emotional-resilience-in-time-of-crisis-how-our-ancestors-dealt-with-climate-and-environment-changes-may-17-2020/. Dr. Bekker is an expert in DBT (Dialectical Behavior Therapy), and provides lovely explanations of emotions, mindfulness, and DBT.
