When i am confronted with an array of vaguely defined symptoms I follow the protocol of looking for the most likely causes to the least likely causes. For instance you mentioned adrenal fatigue and candida or PTSD, and that immediately suggest to me that we need to test you for hypoglycemia, which can be treated by going on a hypoglycemic diet.
Investigate the link between most of your symptoms with hypoglycemia and I am confident that you will be able to find some reasons and treat yourself.
