People need social contact. Even if conversation is hard or unpleasant for you because you’re asocial, or suffer from social anxiety, or have a personality disorder (me, me, and me), etc., you still probably have the drive to make friends, although it might be buried. So compromise: for those days when you need to stay in, get acquainted with a fictional character. It’s okay to substitute fantasy contact with the real thing sometimes, as long as it’s only sometimes, and you’re careful not to fall too deeply into your daydreams. (If you find that all you’re doing is dream and it’s keeping you from knowing real people, this strategy isn’t the best one for you.) Imagining yourself talking to someone who doesn’t exist when you’re lonely doesn’t make you delusional. In fact, it makes you similar to a lot of other people.
