I've been living in my own apartment for 12 years now, and apart from a short period of a few months I lived alone. I was never totally alone though, since I work, meet my colleagues on weekdays, visit my parents on nearly every weekend, and meet my friends and acquaintances. I think I would feel a lot more lonely if I lost my job and couldn't visit my parents for a longer period. The way I live now I don't feel lonely, or maybe a little bit. On the other hand, if I lived in a relationship, I would definitely feel overwhelmed sometimes, anxious of not doing my routine, being deprived of most of my special interests.
