Mtp I know a young lady who was a big girl, always beautiful and confident but had weight issues. Once they sorted out her thyroid issue she started losing weight. She feels better physically. She didn't have her thyroid rremoved, though. Anyway, I'm thinking of you too and hope you feel better and better as you heal.
'Chin up' seems a jokely statement, but I bet you haven't lost your sense of humor.
Take good care of yourself.
