This sounds like one of the situations where you really need a doctor.
Organic Parsley tea just ain't gonna fix this combination.
I second the idea of endocrinologist.
Frustrating but don't give up. Someone will eventually rise to the challenge. If I was a Dr I would sure like to meet someone like you; a complex case on the one hand , and on the other a healthy active lifestyle and a real strong wish to be WELL. Instead of a common ailment accompanied by a passive attitude to treatment and health/wellness in general.
Thinking of ya...
