Sorry about your sister. My thyroid is fine, if you’re implying it might be that with me. My TSH was 1.8. I feel like my brain might be magnifying the extent of these, and could do with coping strategies. Even my own family have said I need to stop complaining about my health and to get on with it. IgA is normal, so I don’t have anything autoimmune going on, otherwise those would be high.
