Have you tried any of the following? Ayurveda. Traditional Chinese medicine. Naturopathy. Integrative medicine. These four branches of health sure helped me. Some medical doctors (M.D.s) practice integrative medicine. You can find one on IFM.org I really think you should try one of these for your health. I know other people who went to doctor after doctor, and they could never find anything wrong with them. Then they went to one of these people and finally got the help they needed. Maybe you should do the same thing.
Dear Father God and Lord Jesus, I lift up JasonDDDD to you for complete healing of whatever is causing him to be exhausted and easily out of breath. May he pray without ceasing to you and Lord Jesus. Please increase his faith in both of you and grant him good health. In Jesus's name, I pray.
JasonDDDD, I am praying for you
