GERD/anxiety/breathing

Hi, I am a long time reader but first time poster. I have had my symptoms since August of 2009. Today I hit my breaking point and was hoping to see if anyone out there has went through something similar and if so what did you do? In August of 2009 I went to the ER twice for severe chest/back/abdominal pain. The first time I was told they were pretty sure I had an anxiety attack and sent me home with Xanex. The second time they told me that it was still anxiety and that when I come in for anxiety it takes them away from actual sick people. Once again I was sent home with Xanex. For the next few weeks my pain got worse but I was embarrassed to go back to the hospital. 4 weeks after my first ER visit I got so sick at work for the first time in 5 years I asked to go home early. I ended up passing out from the pain and was taken to the ER by a coworker. By then I was throwing up blood and was in the worst pain I have ever had. Turns out I had severe Pancrea***. She was told by the Dr to call my family because they weren’t sure what they could do since I waited to long to be treated. I ended up being in the hospital for 8 days and then had my Gall bladder removed (the cause of the Pancrea***). Ever since then I have been a complete mess. I now truly do have very bad panic attacks that are brought on by GERD and trouble breathing. This sight has eased my mind several times. I don’t know what to do about my GERD symptoms, I feel debilitated. I have constant chest and back pain on my left side. Have had a nuclear stress test, multiple EKG’s, chest x-ray’s and blood work…all normal. I cant even make my bed with out getting out of breath and my heart feeling like it is beating out of my chest. I am now affecting the lives of the people I care about. Yesterday I went to a baseball game and had to stop and rest three times before getting to the ticket office. I couldn’t breathe and my heart was racing. It ended up getting so bad we left for home before the game even started. I ruined a fun day out for my family. It took hours before I started to feel better then I just went to sleep. It started again today when I drove to the grocery store and I was out of breath before I was even to the door. I don’t know what questions to ask my Dr. anymore. They say my heart is fine and it is all GERD related. This breathing thing is getting worse and is affecting my life. And after the ER sending me home twice while I was really sick makes me think they are missing something serious again.  They have tried switching meds various times and now I can't tell if the symptoms are really GERD related or a reaction the the new meds.
