Hi

First, do check out "The Thyroid Solution" by Ridha Arem. Dr Arem has helped people with "incurable" depression by taking a very close look at their thyroidal activity.
I belong to Kaiser Permanente and had to sidestep my regular doctor (who is a *wonderful* personal physician) in order to see an endocrinologist (recommended strongly by Dr. Arem).
Arem, it should be mentioned, is an integrationist. He believes that conventional antidepressants have their place in dealing with depression, as does meditation techniques. He doesn't mention Qi Gong but, I suspect, that's because he just hasn't run across it.
Beyond this, I recommend that your friend get 2 books, both available from
www.abebooks.com (1)Self-Creation by Dr. George Weinberg Your friend will need this book to get a good view of what works and what does not work, generally, in psychology.
(2)Six Pillars of Self-Esteem by Dr. Nathaniel Branden Your friend can use the practices in this book, along with those in "Self-Creation" to combat perhaps 50% of the pernicious effect of depression.
One caveat:books or tapes are of limited help if there is a biochemical problem. Please ask him to get Dr. Arem's book and to study it thoroughly.
best wishes,
Mike
