No its not impersonal, sometimes you need to work things thorugh privatly first, so its a good idea to refer her here, let her abosrb the info and then talk about it. Bare in mind she may think your nust for thinking she has a problem. Does she even know about eating disorders? I didn't think I had one untill I did some research, I just thought I was being weight concious. If she has been bulimic (she could also be anorexic, or ednos bulimia is only if you binge* then purge) will probably feel really attached to it, like she cant stop otherwise she'll get fat. She needs therapy and someone to be there for her unjudgementally. But people with eating disorders can be very sneaky, I know that I tell everyone i'm getting better and make it look like i'm taking posotive steps, but really i'm just lying and being even more deceptive so I can keep on doing what i'm doing. Its a sad little world, and if you can rescue her she will be forver gratefull (when she better, she may hate you for a while, but its only a phase) hope all goes well, xoxo
*binging is when ou eat uncontroably, like up to 20, 000 calories in one sitting then either purge, excercise or take laxatives to rid your body of the food and calories. The fact she is merely taking laxatives and purging may be symptoms of ednos or anorexia, but her doc will diagnose her properly
