You have been abusing your adrenals with a lot of stimulants, and the stress did not help either. I would not be surprised if they had you on steroids when you were young for your back issues, which would have contributed to your adrenal issues.
Looking at your list of things you have been taking I noticed you are using a lot of hormonal substances (DHEA, Armour, Isocort and progesterone). You really have to be careful when using these because they can easily lead to more problems including hormone imbalances and glandular atrophy. You are best to avoid these altogether, especially the progesterone. Read some of posts on the dangers of progesterone creams. If you have been on any hormones for a while though you cannot go off suddenly though. Levels must be slowly decreased.
