All of my relationships have a level of discomfort to them. Even the one friend I have who I feel does understand me, still doesn't get me. I think all humans probably feel this way, but then again, maybe they would rather not be known...... I think being placed in a body, as we are, is part of the reason we feel so alone; like one spirit being divided into billions of pieces, causing a disconnect. I've always thought of it like that. I keep thinking I should find a way to volunteer, but I always chicken out. That might be one way for you to gain a sense of purpose, too. Sorry if this is not exactly what you are looking for, these are just the thoughts that came to me.
