Shar, I am glad this helped you realize why you might be feeling the way you are. I don't know if your dr. has talked about you seeing a endocronologist but if he hasn't you might ask him if it would be appropriate in your case cause they specialize with the thyroid. You might want to ask your dr. if he has done a TSH and a T4, if he has done the tsh but not the t4 you might ask him if that would help determine if you should be on any type of hormone replacement therapy for your thyroid or thyroid medication which would in turn help your mood and make you feel alot better if it is needed. I am hurting and also taking care of my mom so can't write much more today but hopefully I can be on more tommorrow. God bless you, (((gentle hugs))), Karly
