Tired of GERD/Anxiety

Hello, I am a 29 year old female who has severe GERD and anxiety. I started haveing problems with acid reflux when I was 17, I had an upper GI endoscopy done. The results were that I had some irritation spots but nothing immediate to worry about. I took prilosec and it seemed to work well and eventually weaned myself off. In the meantime I was experiences some anxiety and was diagnosed with generalized anxiety disorder and started to take paxil and after a few years switched to Lexapro. I did not like the medicine. I had every side effect listed and had major water retention causing weight gain. I weaned myself off that medicine and was doing really well up until about a year ago. I've started to experience some anxiety and once I weaned off my anxiety medicine, my GERD came back in full force only much, much worse. In additon to abdominal pain and reflux, I have been experiencing severe chest pains that run into my back and armpits. It comes and goes throughout the day and has been steady for almost a year now. I would prefer to stay away from prescription medicines if I can find an herbal remedy that works. I don't know much about homeopathy and found this on the website. I am very interested in some ideas on how I can treat my problem holistically.
