Hey there,
I don't have personal experience of commuting, but I do currently keep my car at university. I had to pay £36 for a parking permit for the year for this, but over summer I have been going back and forth from home back to Sheffield so it's been worth it for me. Some accommodation has parking but this is often a lot more expensive, and to be honest, you don't need a car if you live in the city centre of Sheffield if the only places you're going are town and uni. The transport links are really good and essential places are in walking distance. Your car will be fine at home for you to go back and use it, or you could sell it and use the money for living costs.
Budgeting is probably one of the most difficult parts of living independently for me, as I'm somebody who eats a lot and not in a very structured way! As for gyms, I would recommend looking into gyms in the city centre and seeing whether you think they'd fit into your budget if you did move out or whether you'd struggle to afford to live the same way that you currently do. I've been a member of a gym in both years that I've been here and have fit them into my budget fairly easily, as there are some cheaper ones about!
You are able to apply for DSA (disabled students' allowances) when you're at university, which might be a reassurance if that's something you were worried about. They can not only give you funding, but depending on your disabilities they can give you alternative aid such as giving you lecture slides in advance on Blackboard, giving you tape recorders to record and listen back to lectures, giving you a certain amount of taxi rides, giving you a laptop/any other specific equipment you require, and so much more help tailored to your specific needs. I would certainly advise you to look into that, my friends that I know who've applied have found it extremely helpful!!!
Independence is great, as well as being right in the middle of all the fun things that are going on. But there are pros to commuting too, especially like saving money. I know that
@annablagg has commuted to university - Anna could you give any more advice from your point of view?
Hope this helped,
