I strongly encourage you to consult a naturopath, herbalist, practitioner of TCM, somebody who can work up a program
for you. Individual herbs aren't how herbalism is practiced, instead combinations are used. It would be something directly for anxiety, something for depression, something for your adrenals, possibly something to clean out you liver, exercise, meditation, diet. It's very unlikely one herb will solve such complex problems. It's more of a process.
