I find I cannot do bookkeeping for my business without major stress to my brain that is a heavy feeling in the top of my head, pressure inside my skull and a blackening out of being able to think logically. I have to stop as it is scary as if I'm going to have a stroke. There is nothing left to give. Pure exhaustion mentally. I am at 7 mg and I have had this head feeling over a year I am so aware now of the extremes of the stress depleting me. Has anyone seen another kind of doctor such as an endocrinologist?
