Stress and anxiety can result in weight loss. It could be a result of not eating as much, not absorbing nutrients as effectively due to the stress and anxiety, probably other reasons I'm not aware of. Also, don't hold so much weight (ha, see what I did there?) on the comment by others. It's their opinion, not necessarily fact. You already got good feedback from the results and your doctor, you were feeling better, and then, bam, a comment has you worrying. Trust me, I know it's hard to think positive when HA acts up. Hope you feel better.
P.S. Has anyone noticed that they can be feeling really bad - pains, anxiety and whatnot - and then coming on here and reading or posting comments, that they feel better? I was in a bad way before I made this reply and now I feel a little better. Thank you burgundy.
