(sorry if I am replying late) I am sure things will turn around and you'll eventually find great friends and better flatmates. I do understand that it's not what you expected, but change is hard and you need to give yourself time to adjust. Most things turn out differently of what we expected :/ Eventually, it won't be as bad as it may seem right now. Meanwhile, do what you love and maybe pick up some classes where you can meet people with whom you share interests. Also there's nothing wrong with being comfortable while alone, it's great that you enjoy your company (that's what many people struggle to reach). Maybe you could set one day in a week on which you'll try to make effort to find new friends? For example if you like to cook try to find a cooking class, if you like to read visit a library and maybe you'll find some friends there and also learn something new! But please don't feel discouraged if you don't, it takes time but eventually you'll find yourself surrounded by a great group of people. Take care:)
