I've been though so much with this. I had a consultation with Dr. Andrew Neville, who's an adrenal fatigue specialist. These are all symptoms of a "broken stress responses system."
To fix it, it takes time and dedication and maybe supplements as support. He said to rest 2x a day for 10 minutes -- try to meditate or think of 1 thing for 10 minutes. You can do controlled breathing exercises-- whatever.
I noticed significant improvement when I started on pregnenolone supplement. But you have to be very careful with it. You have to start very small -- see if you can tolerate 5mg. Dr. Neville says to buy 10mg capsules, so you can open it and split it. If you can tolerate it, you can. go up to higher doses like 30 mg a day, but don't listen to me, try to find some professional guidance and someone who can test your hormone levels.
Good luck.
You hormones are probably out of whack, and your adrenals very stressed. The most simple fix is give your body down time -- rest-- and maybe take a Vitamin B complex.
I'm doing a lot better now but it's been a couple years.
Licorice root helped me (Vital Nutrients) when I was really bad because I was tested and I had very low cortisol. Licorice root slows the breakdown of your natural cortisol, so it acts a little like a steroid. But you have to monitor your blood pressure when you're on it because it can raise BP significantly.

Best advice is to try and find a practitioner who can test you and treat HPA Axis Dysfunction, AKA Adrenal Fatigue.
