Great post, Suze. However, I don't think that depression is
always a disease. I think there are other health factors that contribute to low serotonin, depression, etc. For instance, we know that exercise creates endorphins and elevates mood. We know that if you don't feed your body properly, that your brain will not have the proper fuel to run at it's best. Sometimes changes in this direction can go a long way towards helping someone feel better.
And for instance we know that low blood sugar contributes to light headedness, fatigue, short temper, decreased memory recall. Isn't that a change in brain chemistry? But you can mostly fix that by eating properly.
I get that you are mostly addressing more serious, long term depression, and chemical imbalances in the brain that contribute to that. I agree with you. And I have nothing against meds.
I just wanted to point this out, as well.

Perhaps for the more mildly afflicted.
