Can you take a year out to save up as much money as you can? Are you unable to take out a maintenance loan? Have you looked the possibility of things like a flat share?
I have had the experience of commuting 2 hours, door to door to a hospital placement 9-5 fulltime for a few months. I was fine with it because I knew for sure that it is short-term so it didn't affect my studying as much. I don't think I could've done it for a whole academic year let alone 3 or 4 o.O
I would prepare everything the night before, wake up at 5:30am and come back home at 19:00-19:30. But I understand uni isn't a fulltime job and you have half days, days off, study leave etc...so everyday might not be a a 14 hour day lol
What I recommend is trying the commute, I tried it for a few days and realised it was worth it for me over finding short-term accom which was expensive.
But honestly, it might be just as hard struggling with a time consuming commute vs a financially struggling student. Both are a struggle ygm
