Thanks for your answer. I'll try to find the same kind fact sheet from emephobiahelp.org in French.
Most of them we'll be supportive, I am sure of that. I think they will be a little bit off sometimes, and not understand fully, but they'll try, and that the most important. We're also very open about mental disorders. My grandfather was a psychiatric nurse ; so I know I won't have to face stigma and judgement (which is a big relief, even if It took me years to understand that, and my family doctor had to remind me of that fact). Also, we are a very close. We talk to each other a lot. Something that is dislike with my family, it that they also about the others they worry about. They believe a little bit too much that we don't need secrets in a family.

It's never with malice, though, so I know it won't be bad, but I'd rather tell myself, with my own words. We know how it works if it's someone who tell someone else, then who tell the other. At the end of the chain, there's a lot of things that are quite different, even if they tried to be as accurate as possible. I know they are observant, too. And even if I don't know if they saw that I fear v*; they definitely saw at least the effect of the anorexia on my body, since I lost a lot of weight this past 6 months. I'd rather correct whatever conclusions they reach on their own.

And at the end of it, the constant lying, hiding, finding excuses to refuse to go to big family diner (we're 25 at this kind of party, that's way too much people for me to be comfortable and eat, even if I know and love each of them), or other events I fear, makes me feel even more anxious, I hate not being totally honest with them.
