I'm sorry, but that is a story that degrades all of us. Not only do I doubt its veracity, but also if it is true then there probably was nothing other than a psychological sickness. Which is what we are all accused of having in the first place, and it does a lot of harm to a lot of us here.
Telling someone they can think their way through a toxic illness is what can cause psychological problems in the first place. Your story is what I am told every day by my family, even though I explain to them that that is how i ended up so bad, by ignoring my exhausted body crying for nurturing.
