I agree with all you are saying on university, went myself as a way to escape at 17, very young in Scotland as can go after Highers. 4 year course.
Ended up repeating a year due to anxiety / depression, 'burnout' they called it at the time in the late 1990s, trying to work my way through it too to pay for it, as well.
In those days the grant was awarded a repeat year for medical reasons, nowadays can't see that happening. I got a 2.1 in the end but it was hard, and the degree, in environmental science, seemed a good idea at the time but was in hindsight quite a depressing choice!
