Does it not bother you sharing a house with people. I admit openly as well it does get a bit much being on you own a lot of the time but I couldn't be going back to all that tbh. When I was in hospital we had to share the entire ward with everyone including the showers and bathroom. That sort of thing.. When I lived at home I would be constantly having people on top of me. You couldn't even go in the kitchen and make something to eat with out being bothered by people. Being woken up, that sort of thing.
It depends on who you live with - once you've found the right people, being in a houseshare is great. In my flat I have an en-suite, and my two housemates - who are also my best friends - have the main loo to themselves. We're very open with each other, to the point we can just go into each others' rooms whenever. Occasionally they use my en-suite while I'm sleeping (usually if they both need to use the loo at the same time) and I don't even know until they tell me the next day
The main advantage is cost; I could afford to live on my own but being in a house share saves me probably £400/mo.
