That's how my son feels too. He, too, is at Lancaster, and really hasn't enjoyed his Uni years. He just wants to get it over now.
The first year being virtually trapped in his room with nowhere to go, nothing to do, shops and cafes closed, library closed except for borrowing pre-ordered books, common rooms locked, entire blocks locked and barriered off, just having the odd walk around a virtually empty campus for exercise really affected him.
He even limited his walks around campus as the security staff were over-officious and would question students walking around as to why during the strict lockdowns (even though they were allowed out), and then again when groups of flat mates would walk around together and were told to split up by security if there were more than 6 in a group during those periods when people were only allowed out in groups of 6 or less (despite some of the campus accommodation being for up to 14/16 in a flat living together).
Then the few times he needed help/support, luckily not MH, but general things like help accessing a computer system, or advice from a tutor, or whatever, and it was all about sending an email and waiting for a reply several days later, as they weren't there to take phone calls, etc. One of his flat mates needed MH support, and again, he just got an email back saying phone or in-person support wasn't available, and just a few links to MH support webpages!
Even now in his 3rd year, he's not really "engaging" with anyone, neither staff nor course mates, and if he has queries about the work, or anything else, his first action is to google it, or ask on student forums, rather than make contact with teaching or support staff. He's never even met his "personal tutor" who wasn't on campus for the first two years "due to covid", so the limited communication was by email.
I think he'll be pleased to get his degree and forget about the last 3 years, which is a great shame when we know so many people who had great Uni experiences during "normal" times.
