Hi, my DD has just finished year 1. She was discharged from camhs a month or so before starting uni.
What dd did;
Registered with uni GP, and made arrangements for monthly weights. Having said this it took several months before they started with it (also did a few blood checks ) and only lasted a few months...
Arranged through DSA to have a weekly 1 hour non-medical helper. Just to have a chat, helps with "overthinking" as you mentioned...
Apply for dsa early, even though you may think you don't need help or you are not sure what help you would need later. Whole process took 5 months ( applied June, got helper in November ).
DD uni is 3 hours drive. This was the max she wanted to be away from home.
It made it possible to visit on short notice when she was upset in the middle of the week (happened once). Would visit maybe once a month and she would visit home once a month. Gradually that became less frequent as she didn't feel the need for it.
DD preferred non catered. She contacted residence and by mentioning her eating disorder they made sure to allocate non catered room.
Academics were /are never an issue for her as such. So is not a source of stress. Obviously this may be different for different people.
Be prepared for relapses/slips. DD was however better in managing them compared to earlier years.
There are some resources available about transitioning to uni with ED
