i only have a second, but HUGS to you!!!
I think I would tell her how much she hurt(s) you by her comment(s) and tell her YES you’ll consider homeopathic remedies, such as chiropractic care, ALONG with WESTERN MEDS…
tell her you are at the forefront of the research (you are! look at you!) in this area and it totally SUCKS that there are no good ‘natural’ remedies for this disease (GERD- the D is for DISEASE)…
then maybe gush about how LUCKY she is not to have to face any of these MEDICAL issues, yada yada and just end it there…
HUG TO YOU!!!!
