To cut a long story short, I want to move out of a 2 bedroom flat in private rented halls whilst my flatmate does not. I have no problems with my flatmate but with the flat itself. Its a high rise building and the flat is on the 25th floor, and the bedrooms are basically cupboards with no windows. Im getting increasingly homesick and anxious just being up there, and cant see out another year like this. i really need to leave. What are my options?
