I can also relate to the feeling of not belonging. the advice I have been given is that I should put in the action in order to start feeling like i belong - so, I need to go and hang out with people even though I feel awkward and like I don't belong, and eventually, apparently, I will feel like I belong.

i find it frustrating. I belong to narcotics anonymous and other fellowships, and many people describe coming into the rooms and feeling belonging. i haven't felt that at all.
