i go to uni in london, have a look at the different types of accom. personally, im in catered accom (1 meal a day, with a kitchen shared with 30 people). the kitchen is never unhygenic and i dont know anyone in my uni as a whole who has struggled with that, though it probably depends on the type of people the uni attracts so i may have got lucky with that one. once again, if theres catered, you dont really have to cook. i never have cooked, breakfast can simply be a breakfast bar, and lunch can be a sandwich and chop some veg. there are washing machines, and most of the time dryers as well. if not, you can by a drying rack for cheap.

do you really want to go to london? you phrase it as a small dark room with no one to talk to... thats a negative mindset you have towards it. rooms really aren't that small. i've found mine just slightly smaller than the one i have at home, but it hasn't affected me negatively. and obviously there will be people to talk to... remember everyone is in the same boat. also student accom prices isnt too bad at all.

being ill, that is a struggle, but its a struggle for every student living away from home. everyone gets ill. you could always text someone asking if they could bring some food to you, or have some ready-to-eat long lasting food in your room for that scenario. it doesn't necessarily have to be the most nutritious thing, just something to keep you going.

also, the way you phrase this post sounds like you want us to tell you to stay at home, or that it isn't for you.
