<p>NO................spend your time worrying about how to keep yourself separated from your friend's mental illness.</p>
<p>I think what you really need to make sure is that the friend at danger doesn't have support. I don't remember where I watched this, probably Oprah, but there are many sites out there that support eating disorders. They have techniques, encourage them, post pictures, etc.</p>
<p>I'm assuming that a friend in danger is calling out for help or tells someone because she secretly wants help and support. Just make sure her support isn't for her to get increasingly sick.</p>
<p>Bulimia can cause permanent damage to the body system. Stop early while you can.</p>
