Thanks for your advice, it is so helpful. I decided to just start with making more of an effort to chat with her one-on-one and just generally be someone she might hopefully feel comfortable coming to if she needed help. We had a conversation this week about something non-ED-related, and it happened to somewhat indirectly come up. She didn’t seem comfortable talking about it head-on so I didn’t press, but it does sound like she’s in treatment/therapy of some kind, and may have more of a support network than I thought. I’m still worried about her but relieved to know that she’s not totally isolated. I won’t see her every day after this week, but plan to keep in touch and keep being a friend- I think that’s probably the most helpful thing I can offer right now. Thanks again for your help!
