Hello and welcome – we are fellow patients here, not doctors, but here are a few thoughts…
Thyroid dysfunction can absolutely cause emotional issues — but if you ever get to a point where you feel like you or a family member is in danger, don’t hesitate to remove yourself from the situation or call authorities if needed.
Usually, patients will see relief once thyroid levels become normal and stable, so hopefully, your husband is receiving excellent care and is being consistent with his medication regimen.
If your husband is willing, a visit with a family counselor might be helpful.
Also, following are a couple of resources that will hopefully be of interest:
GDATF Patient Bulletin – “What’s Wrong With Me – I’m Not Myself Anymore?”
GDATF Conference Video – “The Emotional Aspects of Graves’ Disease” from Dr. Ira Lesser
Wishing you and your husband all the best – please take care and keep us posted.
