I will try to keep this as brief as possible so as to not bore anyone. This is sort of the last battle in a long running battle between my sister and I which started when we were still small. I don't like her, I try to love her as a sister but don't often succeed. Because of that relationship she is accusing me of being an asshole and trying to "get to her" by using my niece of being a proxy. 

I started suffering from an eating disorder when I was 15. I was both anorexic and bulimic. I had inpatient treatment, anti-depressants, therapy, hypnosis, you name it and nothing helped. When I was 18 (I'm 23 now) I discovered a new realm of treatment (also could be called a philosophy) called Intuitive Eating. It basically tells you to eat when you are hungry, food is food and there is never such thing as a "good" or "bad" food. For some reason this philosophy sunk in with me and I finally, finally started recovery. 

I had suspected my niece was suffering from a similar disorder for several years but this was confirmed by my mother. I emailed my niece several articles and blogs regarding Intuitive Eating. I also ordered her several books from amazon about Intuitive Eating and Body Respect by the most respected authors and scholar in the field. 

My sister came unglued and accused me of setting back my nieces treatment by years. I tried to have a rational discussion with her regarding how it helped me and she said that my niece is a minor and I need to keep my "pseudo scientific bullshit" away from her kids as well as some other choice words. 

I swear to god I was trying to help, the books I sent were written by Phds and it's an area where I have experience. Am I the asshole?
