This aniexty is really wearing me down and I don't know what to do, I also suffer from gerd and was on protonix for 3 years. I recently came off off protonix and ever since then I have been having terrible panic attacks. I constantly feel like my chest is empty, and im very aware of my heart and I don't know what to do. I'm thinking a beta blocker could help or something but I truly have no idea....and im scared of medication. I need some help I guess but I don'tknow where to turn I lost 15 pounds also. I can't believe this is all stress....somebody help.
