This is perfectly normal, except for the exhaustion piece.
A few months ago, I couldn't physically get out of bed in the morning. I went to see a naturopath, who told me to go and get blood tests, especially for Vit D and also told me I had run off adrenalin for too long
i did this too after going thru a series of blood test with the dr only to be told nothing is wrong.
i also run on adrenaline, and your adrenal gland needs vit c to function - also turns out i have leaky gut syndrome and liver needs to be unclogged. i also have a brain that won't "stop" a night - keeps buzzing. the naturopath put me thru a series of tests - inclduing for depression and live blood scanning.
anyhow, i'm now on vit c supplement. went on a 6 week gut clean out and detox. am on a combination of herbs to calm the brain to tolerable levels at night so can sleep ... and have gone from not being able to drag my backside out of bed in the morning to feeling great and refreshed.
next week starts the liver detox.
i'd second a reputable naturopath if the doctor can't help.
