Research question (but I'm not a rando gawker! I just don't want to bug my friend!)

My best friend/roommate is in recovery, and because I'm a writer, she's encouraged me to write a fiction piece approaching eating disorder narratives differently. (She and I have talked a lot about how most available fiction narratives contribute to stigma or reinforce myths). She's worked with me a lot on this, but I still have some perfunctory questions I need to clarify that I can't easily find answers to online. While I know a lot from her of what it feels like to be in treatment and what sorts of things happen, I want to thoroughly understand logistics. Right now, she spends so much time in treatment I don't want to waste her limited leisure time taking notes on the minutiae of treatment -- that time is better spent watching Doctor Who together or talking about which sort of moth we would each be if we were both moths.

This is a fiction piece, and not intended to be educational or didactic. But fiction explores ideas, allows people to empathize with experiences they have never had, or identify with characters whose experiences they do relate to. My goal is to write something that 1) helps people who don't have EDs understand what treatment and recovery is actually like, 2) makes people who've experienced it think, "That's so accurate! Exactly!" It would be impossible to tell a good, interesting, well-written story if I wasn't achieving the above.

I know that this might be triggering or just exhausting for some people, so people absolutely have the right to not answer. But if anyone is interested in demystifying and generous enough to share, I would be so, so appreciative!!! I'm definitely sourcing my research from a lot of different places, but I think it would be a huge mistake not to ask a variety of people who can speak anonymously online.

Here are some things I want to make sure I get right:

What staff members are there in Residential? What are their duties? How often are they each around/how often do clients interact with them?
I've visited my friend and gotten to know staff during groups, and of course I know a lot from what she tells me, but I still want to make sure I thoroughly know what the treatment team looks like. Online websites usually only list people like the therapists, if anyone at all, but I know there's a much broader treatment team and I want to make sure I have a handle on what they do and their interactions with clients.

What does a "typical" Residential schedule look like? (Daily, weekly, monthly?)
I know this can vary wildly from treatment center to treatment center, but there do seem to be some consistencies (groups, one-on-one therapy, outings, medical stuff, etc).

How is conversation at meals/snacks conducted? What are some examples of conversations?
I know the typical table rules, and I know that -- at least at dinners -- there are sometimes games (we play a kind of 20 Questions my friend learned at treatment at home), or a question people take turns answering (my friend famously proposes obscure ones that go over really well -- like "what kind of fabric would you be?"). Is this just at dinner, or at all meal/snack times? What are some examples you've seen or heard of?

Medical stuff -- totally understand if people feel uncomfortable with this one.
I don't actually have any questions about weighing, but definitely feel free to offer in case I'm missing things. But I know you have to get labs done before going to treatment, and then they continue to happen while in treatment. Who conducts these labs? Is it the same person or different nurses/specialists? Are they these providers there all the time or is there a dedicated medical day? What sorts of tests are conducted (I think vitamin/mineral blood tests, general urine tox tests, heart rate, etc). I know what all this looks like in a hospital environment, but what about residential? Is it onsite or offsite?

Insurance -- the most frustrating.
Who's in charge of all the insurance/billing/blahblahblah? Do they do double duty in other roles, or are there dedicated administrators for that? How often do clients interact with them?

If you got this far even just reading, thank you!
I genuinely have so much respect and admiration for people battling EDs. For general health stuff, we think of "recovery" as "taking it easy" -- but with EDs, it's going to battle. Recovery is courageous.

If I were a moth, I would be a peppered moth.
If I were a fabric, I would be dark blue velvet.
What about you?
