@AliMonkey Bravo to you and your son for making a decision that is right for right now.
I have been reading all of your messages about children who are unhappy at university. I have two at university and it seems so much more difficult that when I went!
If it is at all helpful, my son dropped out and reapplied through clearing - he got the course he wanted and in fact could have had a few others he considered. It was insanely stressful at the time - but it has worked out well.
My daughter was struggling with so many things, being lonely, struggling with the teaching, not seeing people she loves every day (yeah - that broke me). We had long talks (after many tears), DH convinced her to see the university counsellor who helped change some things for her (but not as much as we wanted), we found some activities that she could go to, to find more of her 'tribe', which helped because she didn't find kindred spirits in her halls. She also talked to someone from her course, which reassured her slightly (which is a long way from fixing - 'I can not imagine doing this for 4 years and getting a job in it afterwards' - but is a first step).
I am torn apart now that they have both gone back as I know the mask I get on the phone / video is impenetrable and I can not visit to see them face to face to reassure myself that they are really OK.
In both cases, I think the pastoral care at both universities has been entirely inadequate.
And I have one more to go = what will that ride on the rollercoaster bring?
