I am personnally not worried about my fillings either. Kind of feel the same about the whole thing of parasites. I feel I am clean and don't have them.
As far as attracting sicknesses, I had a friend who did healing, I went to her and she was great. The other day I saw her mother and she told me that her daughter had to stop healing people because she was attracting all the sicknesses herself.
I have read about Andreas Moritz strong thoughts. Even if he eats things that are wrong for him or the food is not perfect he feels by the positive thought you can make it ok for your body.
Of course you know me well enough how difficult it is for me to accept that, but I certainly want to be open minded to it and it is good to read your post.
I find it funny it even makes me feel more positive.
