I could go back to Oxford where I was last fall before I got ill. There I'd be studying Chemistry. Major downside: Physics in all its splendors and all the Maths that comes with it. I know why I never took Physics and avoided advanced Maths.
I could stay and apply to a more local university and study linguistics in combination with another subject (which one is still open to consideration). Major downside: It ain't Oxford ;) Applying and getting in. Apartment hunting all over again. With Chem I at least know what I'm getting into ;)
So stuck there.
