I know you feel hopeless, but let's keep plugging away at this, okay?
I suspect the reason you were able to sleep last month but not currently is because you stopped taking the progesterone. Out of curiosity, have you ever tried pregnenolone instead? Your lack of sex drive does seem normal to me given your sleep deficit and depression, but I can't help but wonder what the effects on a young male's sex hormones are when he takes progesterone for a period of time. I just remember reading where Ray cautioned against its use for men under the age of 60, I believe it was. I certainly think you getting sleep is extremely important, but I also don't want you to feel discouraged if you've been able to sleep but not see an improvement with your sex drive, you know? This brings me to blood work...
The reason I asked if you had any recent blood work is because you may be driving one or more of your levels up/down and this could be contributing to your current issues. Back when I was taking thyroid, I began having really bad adrenaline symptoms and depression. Blood work showed my once normal cholesterol level had dropped too low and Ray told me "When your cholesterol is so low, your body can't respond fully to a thyroid supplement. Thyroid should cause the conversion of cholesterol to pregnenolone, progesterone, DHEA, and the other neurosteroids, but when cholesterol is too low it just increases stress hormones instead." As soon as I dropped the thyroid, the adrenaline symptoms away.
One thing you could try if you haven't already done so is to keep some juice by your bedside for when you wake at night. This helped both my mum and I fall back to sleep when we would wake during the night from stress hormones.
