WOW! your mother sounds exactly like my mother. I told my mother that she was not welcome in my life anymore just before I started the Candida treatment.
I think you have 2 issues here and you shouldn’t mix them with each other.
1. you have Candida and it may seem to some that it’s all in your head, but it’s not. Even doctors will tell you that it’s all in your head, they are wrong.
2. Your mother is unsupportive, and afraid of change. She would like to keep you in your current state.
Also I have fibromyalgia and I believe it’s 100% connected with the yeast. It sounds to me like your mother has a Candida problem of her own.
