I'm sorry to hear that your daughter is having so many problems. I also have high TSH levels (92.17), and I know how hard it is to concentrate in school. After alot of hard work and many hours of studying, I became a nursing assistant and finished at the top of my class. Hopefully she gets the help she needs soon, it's very frustrating, and her teachers probably don't understand what she's going through, but tell her to hang in there.
I'd like you to talk to magpieanne here as she can help you the best on suggestions. I'll bump this post up to the top to have it visable and hope she will see it to respond.
She's a great source in adolesent thyroid with personal experience. I feel you could message her too asking for her thoughts.
