The basic truth in your post is good. Just wanted to point out a conflict in what you said.
"place my faith in natural healing foods, supplements and herbs that truly are "God's pharmaceuticals"
You put your faith in "God's" works.
"If you want healing and health, then it is YOUR responsiablity and NO ONE ELSE's, not your doctors, not your best friends, not your spouses,etc... but YOURS alone!" Now in yourself "alone".
I think trusting in God no matter what it is, is better?
