Your symptoms are very similar to those I had. I think it all started with digestive problems. I got bad stomach infection while in military. the infection was treated with tons of antibiotics. Now i realised that my stomach did not work well since. I asked doctors a few times (including gastroenterologists) about white coat on my tongue. The answer was always: "it's ok. many people have it. It is not yellow - nothing to worry about. It depends on what you have eaten".
Once you a person had a collapse, burnout, etc. It will take a while to recover. Dr. Jack Kruse explained that "adrenal fatigue" is not actually a fatigue it's blocked PVN (paraventrical nucleos). This condition frequently referred to as HPA axis disregulation. As far as I understand it's a mental condition. It 's a process to fix it, and takes awhile. would not happen in a month or two.
TheIllest, do you have a doc whom you can consult with? I worked with Dr.Lam (also did a lot of studies in parallel). many people here did not have good experience with Dr. Lam.
Healing comes in waves. You stick to a certain protocol and see no improvements and then suddenly they happen and you enter next plateau phase.
I am very familiar with the restless sleep symptom. It was partially fixed when I re-introduced Sugar in my diet. I did not use any sweets before. Before sleep i was eating cottage cheese with honey. It stopped me from waking up at 4-5 am. well i woke up, but could sleep again and woke up more rested.
I still do not have that early morning feeling i had before. when you feel well rested and energetic. Another thing that helped me was massage not a north american one but one you can get in China town. The one that painful. Helps a lot. After a good one, you will have reaction. If you have a reaction, it was a good one. After North American RMT usually i get nothing. What I call reaction: feel sleepy to a point falling asleep while typing e-mail, chills and shivering. After a couple of treatments reaction disappears.
YOU are 22! Your body is strong and full of potentials. You will heal much faster.
