OP if this only started in January I’d think this is what you need to hammer in to every service you speak to.
I'd all evidence you can from the past 13 years : doctors, HV, ask the nursery, primary, current school to summarize how she was (I don’t know how this could be done in a legal way though), contact her friends’ parents and ask them if their children would also be willing to say so (ex: are they a calm group etc).
On another note, I would push the friendships questionings (via the parents may be safer at this point), do none of them have any clue ?

I was assaulted at 21 and ended up pregnant and terminated (I didn’t want to instinctively, but that’s another question, I didn’t feel like there was another option : extremely poor, unsupportive family with mh issues refusing medication I’d basically been a young carer for when my own child in care placement ended at 15 due to passing away - and it was only a couple of months after I’d managed to get away from all that, so causing huge family discontent of ‘abandoning’ them and getting myself into an amazing education opportunity (I was always extremely academic luckily, just not allowed to move, so I was lucky in that sense that getting in was still ok at a high level).
Anyway, sorry for all about my life, it’s just to give you insight into the torture before the decision to terminate, and after that I completely crumbled. For years. And for long years no one knew. My academics struggled but somehow held on ( I’m actually still not done at 32, because of years off, although it’s a v long degree and final year of). I still had friends. I still passed when I did show up to exams, so no one understood.
Sorry I’ll stop now because it’s hard to talk about rn : I moved to England (western European) for the final year last year, and failed it, I crumbled again. It’s my fault in a way because by not talking about it I never accessed the right therapy. And here the new environment was less forgiving, they didn’t know me, and well, it’s up in the air now if they’ll actually let me finish, or if it will be all over and back to 21 with no qualifications (I can’t just repeat back home for complicated academic fine print, or my home institution definitely would have let me - to be precise didn’t fail, I just crumbled and lots of absences was the issue).
Sorry this last paragraph wasn’t planned at all, barely anyone knows about it because once again it’s so horrific I can’t bear talking about it.
All this to say, don’t let her be like me, in the possibility it was a traumatic event. After 11 years of fighting to hold on alone (I do have very close friends) I’m still about to lose it all…
