New to this, needing help!

I have sensed for some time that my diet & Lifestyle needed change. I am overweight, have been dx with fibromyalgia in 1991, and now probable Multiple Sclerosis! I pray and ask for God's help, and He keeps leading me to. And all this stuff about dental fillings and diet. I have been a nurse for 17+ years and don't see the medical community really helping the total person or showing patients that they DO HAVE A CHOSE!
I will be studying want you have on the site, but feel I need some experienced people in this area to help me. What do I first? Where do you find a dentist to replace your fillings? I think I'm O+, but am not positive?
Thanks from Alabama
Sincerely,
