I do understand what you are feeling. I have a personal space boundary around me too. I think a lot has to do with our past and how we learned to cope with various things that happened. Mine was from a rape. I put a wall around myself and only few are allowed in.
I am a outgoing person....however, I know that inside I feel like an outsider looking in at times. it doesn't happen all the time, but it does happen.
I think what has worked for me is to let myself let that wall down at times....opening up about my anxiety and depression to friends has helped a lot. They would mention that they could always "sense" something with me. I would love to know what that "sense" is though.
I do understand
