I do not know what to feel right now. I cannot think very clearly. I took Marty to the vet yesterday. The dr found a nodule on his thyroid gland. I feel like such a bad mommy right now. Marty has been exhibiting the classic symptoms of Hyperthyroidism and I did not know. He has become agitated and he has been pacing the house since his brother past away (11-15-06). I thought that he was grieving. I have to call the vet soon to get the tests results, but I am not expecting her to say that all is well.
