This was Mama Red's post about Adrenal Fatigue in the thread Remembering Different Things for the Same Event
I don't know if this is true for you AND your second paragraph sounds like you're describing my days...there are days when I can go and go and go and then I crash, flat on my behind, and lifting my arms could be the most energetic thing I could do!
When I had tests done for my adrenals and D3 levels, the doctor said he was surprised I could function. My healer said the same thing...and told me there can be an interesting pattern to adrenal fatigue/exhaustion.
I learned that you can actually be both "hyper-adrenal" and "hypo-adrenal". You can pour it on sometimes, and be, as my family used to say "laid in lavender".
I've been this way for so many years that I didn't realize that what I was doing when I was abundantly energetic I was pushing my system, and hard, and then it would crash....it could only "kick it up" for so long before I crashed again. Then I would be flat on my back, apparently rebuild, then do it all over again.
Another odd one to me was that since my adrenals were so stressed, they actually kept producing at night because of a survival instinct. I was so low so frequently, that my adrenals "stayed on" to make sure I had the hormones just in case.
Because they stayed on during the night, I wasn't sleeping worth a crap!
It became a vicious cycle that became a bit more manageable when I started on adrenal supplements (followed by thyroid supplements after my adrenals were stronger), stopped giving in to my propensity for trying to get everything done when I felt strong and allowed myself to do a little bit at a time. Retraining myself has been, to say the least, interesting!
There are days I feel horrible for the DH since he is in better health. And I also know I'm learning how to NOT carry the sickness and sadness of others. I'm very prone to picking people and situations up and carrying them, which in turns wears me to a frazzle and leads to debilitating periods that cycle back in on themselves.
Years ago when a doctor recommended antidepressants I got really p****ed off and said "you'd be depressed too if you were living like this, not the other way around!"
