I generally feel a hard to describe sense of being 'off' I will be dizzy/floaty/off balance. I get numbness/tingly feeling sometimes. Palpitations, hot and cold flashes...general fearful thoughts of having a health episode/dying.
It is really hard to deal with, and exhausting, so I know your frustration.
Continuing to simultaneously treat the physical issue (GERD) with the anxiety will bring about
the results you need.
I have much better management now than I did at the peak of my issues, so know there is hope, and progress will be made.
With encouragement,
S.C.
