Ginger lady, no real advice. With DD starting uni next year this has been worrying me...
DD was under camhs for a short while when she was 14. Discharged as we thought everything was fine. A year later I realised she had restarted purging (and in retrospect had at least for 6 months, did she ever really stop??).
Anyway I did just ask her straight out, and I think in a way she was relieved "she was found out".
The uni DD is planning to go to does seem to have good services for MH and on their website it mentions eating disorders as well.
I know that at her age they can not talk to parents but parents can still talk to them..When I was worried about my other DC at uni I emailed Student Wellbeing Services and they did phone DD to check on her.
There is an information file on freedfromed that camhs emailed us, it's more about starting uni but maybe helpful?
And for what it's worth, I have already been checking on hotels near dc2 uni so I can visit frequently to try and keep an eye on her.....
All so difficult as ED just seems to make someone sneaky and in denial.
