Oh yes. I have many acquaintances, but no real deep friendships. Even those who I am closer to don't really know me as well as they think they do. I'm not antisocial -- I do like people, and can be quite friendly, but it's mostly on the surface. No one is truly very close to me, and they don't seem to want to be. Apparently I'm "too moody" for a lot of people, and they don't want to put up with it.
I used to have a wider circle of friends, and had a lot of people that I considered close friends, but have lost most if not all interest in socializing at this point. I very rarely go out anymore, whereas I used to be very active, going out several nights a week with one group of friends or another. But I've lost interest in a lot of things, so nothing's very fun anymore. Now my schedule is basically go to work, do chores or waste time at home, go to class/do homework, and sleep.
I'm starting to think I should just accept the fact that I will never have a meaningful relationship with another person, and learn to become comfortable being alone for the rest of my life. It makes me sad to think of this, but I can't imagine ever feeling good enough to return to my former level of social involvement.
Bleah, sorry for the depressing post. I'm just feeling pretty down tonight.
