Omg it is so tricky, thank you for being so honest! The rent market at the moment is so hard to get around but if you can find a place where you can afford it and still find the energy and money to keep yourself afloat then it is definitely something you should consider. It's so hard to leave family especially I'm sure if your parents aren't completely thriving. But I do want to push the idea of self care, if moving out will give you some more brain space and a bit more quiet then it is definitely something to look into. Try student accommodation, it is still quiet cheap and it is right next to which every uni you're at. Another option that I personally like is share houses (I'm a very social person though).
I hope this helps and good luck! :))
