I certainly understand what you are saying. The internet by its very nature is mostly introverts. I am very logical, and introverted. A scientist. I usually gravitate toward artists who bring a totally different worldview to my table.
First comes self-acceptance. Self-love. When I realized I needed friends, I made a logical effort. I worked the problem. Joined some groups. Met my wife and was deleriously happy. Then my wife died of cancer. My world became very small.
Right now, I am at the point I need to reach out to others, sober others, and that is one reason I am here on this board. Have you tried going to any AA meetings to find fellowship there?
