I was diagnosed with hypothyroidism in 2007 and never got treated for it. Now I have been diagnosed with subclinical hyperthyroidim and I am losing my self control. It all started in July os August when I had a serious panic attack out of the blue. For the past 6 months I have been dealing with anxiety, panic attacks, rapid heartbeat, feelings of waling in a dream, crying spells, mood swings, shortness of breath, depression, intolerant to heat and cold, weight loss, brain fog, itching, fear, paranoia and total despair. I was put on methalazine (I think I spelled that right), 10mg per day. I took one pill and had a major panic attack. Somebody please tell me what is going on. I know that I need to take the medicine but I have medicine anxiety!!!! will this ever end or will I be a prisoner of my fears forever!!!!!!!!
