Im not really sure how to go about this so please bare with me.
My family has suspected that my sister has been making her self sick for a couple of months, but she would always deny it, she is 29 and is very thin.
Last year it got to a point where we were all worried about how thin she was and also her friends were too.
I finally managed to sit her down and talk to her about it last night without the parents knowing and i asked her.
She finally admitted to me that she eats then "purges" the food out the system and to my utter shock she had told me she had been doing this for 10 years but over the last few years it got worse.
Part of the deal that allowed her to tell me this was that our parents were not to know at any cost.
I am a 23 male and have been trying to look into it and to work out what i can do and i promised her i would help her overcome this.
Im really unsure on my next step in what to do as she wont see a doctor yet as she wants to see if she can stop it herself.
What makes it harder is she doesn't live at home so i cant see what she is doing.
Im writing this to ask for advice on everything, i feel like this is something parents should know but she made me promise not to say anything as she worries they will think they are too blame and put her in a clinic etc even though i have explained this is not how they will see it.
Many thanks in advance
