I Want to Be Understood By Just One Person

It seems no matter where I've been, school, church, even summers at camp, always feel like an outsider. I feel like there is barrier between me and others and though we can come close there can never be any real contact. I feel like no one gets me and everytime I'm with someone I can pretty much garantee that we won't be talking about what I want to talk about. Or if I'm with a group I always do what everyone else wants to do. It feels lonely because I always think. What about me? When will someone try for me? In my head I'm not that bad but maybe I'm unbearable to be around in actuality. I don't know. I'm just tired of experiencing life like this. I wake up in the morning everyday and wonder if today will be different. I feel so isolated. I've been living on my own ever since I turned 18. Where is everyone? Lately I have just been excepting everything, going to work and watching my co workers socialize without me, giving me occasional glances and forced smiles so I know I'm still part of the group.
