I wouldn't worry about the university too much at this point.
There are so many ways of catching up with education these days.
I qualified from the Russell group university at the age of 45. I had to do an Access to the Higher Education course to be accepted to uni, as I had a break of more than 5 years of studying.
I am neurodiverse. it was my 5th attempt at getting higher education. When I finally did it, I did it with a bang, with a 1st class degree.
My son did very badly in Y10. I told him, if it continues like this, he should really consider going to college to train as an electrician/gas engineer rather than taking A-levels. I told him it was pointless getting bad A-levels and then ending up with a Micky Mouse degree and lots of debt.
It suddenly spurred my son to try harder.
Then he was crying in the middle of the Y11 as the pressure to do well got to him.
I reiterated my point he could always go to a vocational course. Should he still want to go to uni he could do Access to Higher Education and get into uni as a muture student later. This calmed him down.
My son is predicted top grades for his GSCEs. However, it has been touch and go.
I would say, do what you can to support your daughter's mental health at present. Going to uni should not be the priority at the moment.
