(Im 20/F) I have been having GERD (too much acid) with nausea for the past one year and 1 month. To the point where i wasnt able to get out of bed for a year, and couldnt walk, nor eat (or barealy with huge nausea). I have been on ant-acid medication (PPI) for the past 6 months, which helps a lot, but i still have a lot of nausea, especially in anything slighly anxiety inducing situation.  Which to me seems like its any kind of situation. Anytime i go out, even for a small walk i feel much worse, and i feel like i will vomit anytime. But even at home i feel nauseaus most of the times. I even had an edoscopy which came back clear. i tried diets, they helped a little, but soon i realized that probably anxiety is a big cause. I learnt realxing breathing and meditation which helped for a while, but in the past days i have been nauseasus all day long again, and my stomach clenches on its own at any time, which makes me feel like i will gag or throw up. Its horrible.. And there is this weird unsafe feeling inside, which now doesnt go away even with meditation. 

I have been going to therapy for 5 months, doesnt help much, and my parents dont allow me anti anxiety meds. 

please give me ideas, i want to be old me, i want to go out and explore and do things without having this awful nausea and sickness.  Is there any hope or any remedy that actually works?
