This is an IMHO extremely important text about breathing and overall health, about the so called "intermittent breathing" and how you can learn how to breathe CORRECTLY: https://www.intermittent-breathing.com/ultimate-guide/ This should also massively reduce your stress level! Please note that the text also says that an emotional trauma can totally mess up your breathing as the respiratory musculature is affected by the "traumatic energy", which is stored inside the entire muscle system, so please also read https://joettecalabrese.com/blog/homeopathic-remedies/post-traumatic-stress/ about a homeopathic remedy for traumas called "Ignatia Amara" (thats the same as "Strychnos ignatii").
