33 years old and already all of that... I think that I'd be heading in the same road if I weren't making the same (or, rather, similar) changes as you. Good luck.
An interesting point was raised in a book I very much love (which, in spite of digging through all my boxes of books, I cannot find) called The Complete Book of Tai Chi Chuan by Wong Kiew Kit. He said (Edit: He was actually quoting James MacRitchie) that we don't really have a good definition of health here in the West. He pointed out that our definition of being healthy is just that we just don't have any major illnesses that interfere too much in our lives. (Begin edit) I finally found the book, and the quote is this, bolding mine:
(End edit)In the West we do not have a measureable definition of health.
There is no medical text book which defines the state of health. There is no monitoring process for when, and how much, we are healthy. We only know when we are unhealthy, because then something is wrong. The working definition of health in Western medicine is when you are not ill...
I'm actually taking an introductory nutrition course this semester. The book is a mixed bag (not from a primal bias, but rather from the fact that it talks about how great clinical trials are vs. observational studies, and how the latter shouldn't be used to make conclusions... and yet, every single page is filled with "x is linked to y" and what have you), but the most telling thing was that its definition of health was pretty much that definition.
Well, I hope that you are able to achieve true health, not just that definition of health.
