@Trunk I did a PhD in a Maths department in the UK, and there was a whole spectrum of people there. And some Cambridge dons whom I met weren't necessarily the most switched-on to non-academic things. I'm not an MD, but from personal experience there are good days and bad days, and it's not always obvious what's going on. So I think a check-up with a specialist probably won't hurt, as there are dysphoria and other non-helpful conditions less than full-on depression.

You enjoyed Quantum Computing at Oxford, got a 1st in MATHS, of all subjects. And now you sound all doom and gloom. Do you think it might be worth talking to a psychologist or a therapist? There might some things like depression or anxiety which sneak up on you.

There's a potential advantage, which no-one seems to mention. Children born in the US and in some other countries get citizenship of their country of birth. Still, this might be better deferred till a later stage of the PhD.
