Its commonly known usually as "Graves Rage" if your daughters are tested for Graves Disease and Hyperthyroidism with a simple TSI test.
At least ask your Daughter if she will get this blood test done....if nothing but to rule it out.
My daughter has almost exactly similar problem . It just came out of nowhere .
Please let us see if we can find a solution to this issue . Anything I find I will share with you and let us compare notes .
I need help . We need help .
My daughter's blood work indicates hyperthyroidism and she became paranoid about 2 weeks ago.
Also , she has a high level of B12 .
Please , anybody with insight , please share .
Unfortunately you might have to get a psychiatric order to get her taken to a hospital. As her mother and if she is so bad, you will have the right to do this. You will have to say though, that you fear she could self-harm or you feel threatened by her. (Even if this is not true, they take that more seriously than just a thyroid issue)
One of the worst things about being hyperthyroid in extreme is the fact it can make you psychotic. Many hospitals now test thyroid when a patient is brought in for psychotic episodes.
Left untreated she may well do something drastic. I urge you to call a hospital and ask her to organise getting her to psychiatric help as soon as possible. You will not regret doing this.
I hope it all goes well.
