I think it is just a coincidence because when I was around 13 years old I had shortness of breath out of nowhere and the doctors said there was nothing wrong with me and it was only happening because I was “ thinking about it to much “ and then a few days After that appointment it just went away completely; for years . But from everything I’ve experienced and researched I am under the impression that it is something neurological. All my blood test show no deficiencies. I thought maybe I was allergic to something because it seems to be worse especially after eating. I can never get a deep breath when I’m focused on it but when I’m distracted by something Else it seems to be much better
