I am sorry things keep getting worse for you - Merrida has advised you with great thought and wisdom as I know she has been following your anxiety issues as well as physical problems all along.
I agree with Merrida. The only thing I will add to the mix today is wondering if any of your Drs. mentioned achalasia; it is rare but you may want to ask your GI Specialist about this disorder?
Please don't get caught up in Googling this disorder; I will add one link and read it with an open mind. I am not a physician and I cannot dx or take the place of your medical team.
