Hi Travis, welcome. I'm sorry to hear that you've been dealing with this for so long. You may also be interested in this related discussion (very long) that @gabrielm started a while back:
- Mysterious shortness of breath: What has helped you? https://connect.mayoclinic.org/discussion/mysterious-shortness-of-breath/

Travis, I don't know if it's too soon to tell, but is the Prilosec helping? Have you ever tried some of the breathing techniques suggested in this discussion?
