Suggest Treatment For Shortness Of Breath And Vomiting

Hello I am 24 yr old male, for the last 4 years I have had a shortness of breath that to me feels to be digestive related. I have been in and out of doctors and have had testing done so much in the last 4 years.. It s really ruining my quality of life. I have had early on a stress test, ekg or ecg, barium swallow, upper endoscopy, it seems like it has gotten worse over the years the shortness of breath is persistent but does get worse at times, I feel food coming up the back of my throat and feel the need to kind of let it out by vomiting tho sometimes it does just suprise me and come up. I am overweight about 5 10 255lbs. Most times at doc offices my bp is high like 140s over 90s, but I do feel quite anxious there. Home monitoring is mostly normal levels for bp. Any other info you need or any ideas you may have would be so greatly appreciated
