Thank you for your comment ALG. I really do appreciate it.
Re the depression and excersize thing. Link:
Study: Exercise Has Long-Lasting Effect on Depression
Excersize just as effective as drug therapy. More research must be done on the matter of non-drug treatments for depression, considering that the WHO estimates 1 in 5 adults have it. However, if you think you might have clinical depression, go see a doctor. When it is a medical illness, it should be treated with medically (with a little help from visualization, or self-hypnosis, at worst, it can't hurt if done in conjunction with medical treatment).
I'll comment on my last post a little later, when I've had a chance to think on this more.
