I have always had (and still often do) an intense sense of loneliness. I never seemed to be where everyone else was, in the room, in the restaurant, etc. It feels almost as if I were caught behind an invisible wall observing my environment and its people from far away. Everyone seems to be there, existing as a human being, but I feel almost alien-like. My therapist says this has a lot to do with my disconnection with myself and that I have a hard time detaching from what is going on inside my mind enough to be "present" among people. It makes sense to me. I never really felt comfortable around others....let alone myself. Keep talking. It is all about finding the origin of the feeling that makes you uncomfortable. When it is brought to light, the less threatening it seems and we know what we have to do to keep ourselves in check.
