Ugh! I'm sorry you are having all these problems.
I just wanted to give a little background of what I went through. I was having pretty severe chest pain and they eliminated any heart problems. They kept telling me they thought it was GERD.
I've taken the papaya and it does help. They DO sell it at Trader Joe's. I've also drank a teacup with 1TBS of Bragg's apple cider vinegar and a tsp of honey before every meal. That helped too. . .I guess it is full of enzymes like the papaya pills. My doctor tried giving me the little purple pills (Prilosic or Nexium?) but they didn't help at all.
However, I just kept getting worse. . .I was having panic attacks too.

After 2yrs of suffering and becoming depressed and starting to think I was crazy, they finally figured out it was my gallbladder!!! Grrrrrr! Early on I had an ultra sound and I didn't have gallstones so they just dismissed the possibility of it being my gallbladder. The problem was it WAS my gallbladder, no stones, just not functioning. After I had it removed all the problems disappeared. Yay!
I guess what I'm trying to say is, have they ruled out gallbladder problems? Lol.
Just one more little thing. . .on our last trip to WDW I developed a little heartburn. . .not surprising since we were eating quite well. But. . .it just didn't want to go away no matter what I tried to get rid of it. After we came home, I mentioned it to my chiropractor. He said that since I had just recently been on a lot of rides my stomach may have moved up. . .I'm assuming giving me a bit of a hiatal hernia. He did this thing where he basically pushed hard into my abdomen and moved my stomach back down. It didn't feel so great while he was doing it. . .but the relief was almost instant. I had that happen one other time since then and I had him do the same thing with the same results.
I hope you can find some relief.
