Hi, OP -
Academic here. I am so sorry this is happening. Sadly it isn’t that uncommon. I will give my thoughts on several strands if your message.
I think it is positive that DS wants to finish the year, if only because this is a medium term goal to keep him going. I would definitely encourage that.
I don’t like to see academics on Research Track used as Personal Tutors and this example shows why. They are usually temporary, not invested in the school, have little to no experience of student life, and as the job title suggests, heavily prioritise research. They don’t have the time or experience to do the PT job right. (That the PT has a heavy Chinese accent is something I would expect a student to cope with, but it is not the crux of this problem)
In my (strong Russell Group) School DS could request a change of PT for personal reasons but this would need to be done delicately. The context below would help
DS really needs to engage with Student Support Services. He also needs to figure out whether he has a clinical Dx. If he does, working with the Office for Students with Disabilities (whatever it may be called) is important. The accommodations they can arrange do no more than level the playing field. It is stupid not to make use of them. An officer from OSD can also advocate for registered students with Mitigating Circumstances Panels and there is a reasonable chance your DS might be finding this helpful
Students engaging with their School Student Support Officer and with DSO are often prioritised for experienced and caring PTs. If DS engages this way, he can then request a ‘more experienced’ PT without slagging off this one.
I agree with all the PPs that students who don’t drink find the ones who do particularly visible. They need to work harder to find their people, but they can do it! A reasonable percentage of UGs are now teetotal.
As @AlwaysFreezing says, a transfer depends on good co-ordination between the organisation of degree programmes and may tacitly require a 2.1 in Y1 also. I think the latter is a big ask for a student in distress.
Furthermore if there is any doubt about the depth of DS’ Y1 knowledge, re-starting will be much more academically sound. Student Finance allows this, and it is much easier to arrange. Everyone understands that you sometimes make the wrong choice. You do need to be able to discuss what went wrong and what steps you have taken to prevent a recurrence.
Best wishes to your DS
