I am a hermit type of person. I love being alone. Being with people bothers me. Fortunately, I can handle being with family occasionally, and can handle going shopping, running errands, etc. Other than that, I have no "in person" social life. Like WerewolfPoet, I have a rich fantasy life, with a number of different "universes." This is fine for me. When I finally was able to live on my own, and moved away from the area I had been living in, I did have a period of adjustment. I left a music CD or a radio station playing all night for several weeks, but I was fine during the day. Even when I lived with relatives I was a hermit. I spent most of the time by myself, so I had no real trouble getting used to living alone. I much prefer it. Living with other people wasn't good for me. We all drove each other crazy.
I do understand that some people are more comfortable with other people around. I just wish that "people" persons could understand that some people prefer going solo. My younger brother's ex-fiancee couldn't stand to be alone, and would make him drop her off at the mine and my mother's apartment when he would go to work, as he worked a short distance from us. Or she would call us to come stay with her for the day. It was a pain to have to cater to her on an almost daily basis, as it interfered with any plans we might have. My mother wasn't about to say no, though, as she wanted to see my little nephew. Eventually my brother and his girlfriend broke up. Her parents got custody of my nephew, and my mother and I got custody of the dog.
I also have to deal with my father, who is definitely a people person, and he can't accept that some people like being solo. He is convinced that introverted, hermit types are automatically unhappy because they are not with other people much. He thinks the only way to be happy is to be with other people, and keeps trying to get me to socialize. I am in my mid 50s and too old to change from a hermit into a social butterfly. Why should I? I like being alone.
Don't worry about liking being with people, but do try to get used to sometimes being alone, as sometimes it can't be avoided. Just find ways to keep occupied when you are alone, maybe use headphones to play music, or use an I-pod or MP3 player, or phone or tablet to listen to the radio, especially at night when it seems to bother you the most. There are ways to deal with solitude if it bugs you, just as there are ways to dealing with being with people some of the time for those of us who prefer solitude.
Anyway, good luck with this!
