So sorry to hear that your mom is struggling, but glad that you found us.
She is certainly welcome to call or email the GDATF at 877-643-3123 or info (at) gdatf (dot) org. We can't give medical advice, but we can provide credible information and support.
You both might also find our patient bulletins and videos helpful. The “What's Wrong With Me - I'm Not Myself Anymore” bulletin (first link below) and the “Emotional Aspects of Graves' Disease” video (second link below) are especially helpful.https://gdatf.org/about/about-graves-disease/patient-education/whats-wrong-with-me/https://www.youtube.com/watch?v=CB8_5rbCso8&t=1425s
Wishing you and your mom all the best.
