I was diagnosed with an under active thyroid 4 years ago, although I had not been feeling well for about 4 years before that. My problems began soon after my lovely mother in law died after a long illness. This was then followed two years later by the suicide of my husband, which i witnessed and i have been diagnosed with Post Traumatic Stress Disorder. My blood tests for my thyroid come back fine, and I have had scans and all sorts that show nothing sinister, but I still don't feel right. My temperature seems to be on the low side between 35.5 and 36.1. Could it be adrenal fatigue and where do i start regarding treatment?
