Hi, OP -
So DS hasn’t enjoyed the whole uni thing? I am not asking you to compromise his privacy, but has he been more specific? Most importantly, would quitting now be a positive move or a negative move?
Letting go of a subject you hate, moving towards something you would enjoy more - or even having a plan for exploring what that might be - is great. Possibly being depressed, fleeing a bad romance, internal pressures about your sexuality (more of an issue for YP than most adults realise), MH or social problems is not.
In some of these cases a fresh start can be the right choice, whether that is a gap year, a job, or a new university. But it usually takes a bit more self knowledge than what you’ve related.
There is nothing wrong with feeling stuck or having problems you can’t articulate. But in those cases, the preservation of choice offered by a suspension of studies can prove most valuable. From how you have described DS, this is what I would want for my own DC at this point.
I would be make it very clear that it’s all about keeping one more choice open. I would also want DC to be talking with a trusted adult, whether a parent, other relative, tutor, family friend, academic coach or counsellor, to understand more about what is driving them and how to move forward enthusiastically, whatever that entails.
Best wishes to DS and your family. I am sure this isn’t easy to watch.
