Hi Kristiemarie,
Many of us who have a bp diagnosis also have thryroid problems. On my mother's side of the family, my grandmother, mother, sister, and I all have take meds for hypothyroidism. All of us have/had some type of mental disorder as well. I'm not sure that thyroid problems can be mistaken for bp, at least not in my case, the two just happen to go hand-in-hand.
I can understand why you are in a bad mood-lots of stuff going on in your world! Taking care of dogs can be quite expensive-my two dogs cost me way more at a vet visit than a dr's visit for my children.
