Hi there Zesty,
I'm sorry to hear you're not having the best time at the mo - this must be stressful.
Nobody can rightly tell you what the right choice for you is, except you. I would start with considering where your unease is coming from - is it the course, the uni itself, or something outside of all that such as feeling anxious in general, or not having met people like you yet? Is there anything you can do, join or get involved with from now that will make your uni life more enjoyable?
If you've given your current course a chance but are defo not enjoying it, then you can always choose to take this year out and reapply in the main cycle in 2026 for 2027 entry. Just be aware though that there are many things you can do with a law degree and so if the course content isn't a problem for you then you won't be trapped into doing law as a career. You can still go into Politics or government with law if you wanted to.
I can't comment on how your uni will advise on loan and accom leases - this will be something firstly to ask your personal tutor, and secondly to ask your uni's finance/money advice team. This will vary subtly from uni to uni so its not something anyone can advise on outside your institution.
I hope some of this helps, best of luck with your next steps 🙂
