Hi, I suggest you read the Naïs SOUBIROU method is simple enough to understand. This explains an exercise to do (it looks a bit like a meditation blend EFT). The booklet is called "Se délivrer de la boule au ventre" you can not really find out in KDP Select or e-book. The raissonnement explained that helps to release internal tensions we accumulate after the anger and aggressiveness that we contain within our being we feel soothed and relaxed because we breack free from tensions. I really advise people stressed and anxious to apply this method. Personally, I found the wellness thanks to that.
