I first found out my sister was suffering from bulimia about five or six years ago. Her friend had told my mom, and my mom told me to watch out for her. After a year or so, she seemed to have stopped, so I stopped watched her so closely. Now, my sister (who is very thin), definitely has some sort of body dysmorphia. She is very critical of her body, and very unhappy with it, which is ridiculous. The past few months, I have noticed that she has been especially critical of herself. She is constantly making comments about how she needs to lose weight, and I have noticed that she has been binge eating, and then going to the bathroom in the house farthest away from where people are. I am pretty certain that she is making herself throw up. I tried to talk about it with her, but as with every other time I tried years ago, she runs away or yells that she doesn't want to talk about it. I tired in the car once, where she couldn't get away, and she just stayed silent and wouldn't say a word. I don't know what to do. I told my mom I was worried with her recent body issues, but not that I knew she was throwing up again. I just don't want my sister to stop talking to me because I have told someone. We are very close. I am just so worried about her and I don't know what I should do. If this has been going on for the past few years, she is probably doing serious damage to her body, and I don't want anything to happen to her.

Does your mom know what's going on with her? If not, tell her. If so, why hasn't she gotten your sis into counseling?

An eating disorder is not something that you are equipped to handle. You need to get an adult involved who can get your sister appropriate help, which can include counseling, physician, a nutritionist, and in or out patient therapy. This sounds like a lot of bring down on a person, but think of it this way... is your sister talking to you worth her life? If your mom knows about the eating disorder, and is not intervening, you may need to approach another trusted adult.

(had to spread the rep wondergirl)

She needs to speak to a professional. Like Kcomissiong said, if your mom isn't taking action, another adult (maybe your dad) needs to. It has been going on for so long now, that she definitely needs some serious therapy.

You're a good sister, and a caring one. The best way to care right now is to let a professional take over.

My mom doesn't know that it has started up again. And at this point, my sister is 24 years old and I don't know if we can really force her into counseling. I'm not sure if there is really much I can do, which is killing me.

If you know any really high calorie foods that she loves buy them and give them to her or just find a bunch of stories online and tell her what happened to these people and that it is a very serious problem that she could easily die from and get all of the people that she loves the most into the room and have each of them tell her that she needs to stop because if she does die they would miss her do an intervention type thing.
