I also have panic attacks and anxiety and reflux. I don't know which came first
but what has helped me a lot is lorazapam for nerves. I also take ranitidine, pepto bismol, gaviscon and try not to eat too many carbohydrates. I didn't stay on PPIs because of side effects and they weren't helping much. I don't want to have the surgery if I can get by without it. I know people with anxiety often don't have as good an outcome.
I hope you do all you can to get your panic, anxiety etc. under control before you have surgery. The lexapro may be just what you need along with meditation and relaxation techniques. You may feel so much better that you don't need the surgery. It's a daily struggle and it's hard to do. You are so young and have so many people that need you. I hope you find some relief very soon either with medication or surgery so you can be at peace.
