I too have stomach issues, I am pretty sure it is because of stress and worrying, I know it makes things worse but I am having tons of issues accepting this as my life. The doctor I have is HORRIBLE, we have a hospital that owns all hospital in 45 mile radius, So they all stick together, I am calling tomorrow to try and get in with a doctor which is 2 hour drive each way.
Hang in there, Even though I do not post much I read and lots of the things help me. I am just dealin with bad depression so I don't like to share, but I'm working on that :-)
I hope all goes better
