I thought I was the only one that ever felt that way. It was many years ago when ICC was the only place to play online, and I was exactly the same. I could play bots, but not people. Losing to a bot was one thing, but another person? No way! I ended up writing about the online chess experience for some class I was taking at the time. I think that what's finally did it for me. And since that time, I basically accept losing, failure, as a part of the process of learning and growing in all areas of life. Some years later I played in OTB tournaments. These would be weekend events where a game could last 4 hours, and you'd play two or even three in a day. It could be pretty grueling. And of course, you have to accept your losses. It's an amazing experience to be an adult and lose to a child or teenager. But yes that's happened to me more than once. I'll also add that it's amazing to win an OTB tournament. Once I played in a large weekend tournament, six games over three days. I was in the under 2000 section (my rating was in the 1600s), and for some reason, I simple could not lose. Even in games where I would have a losing position, I would still manager to win, or in one case draw. I was bullet proof, and it was such a wonderful feeling -- felt like I was walking ten feet off the ground. The only tournament where I've ever won a cash prize, too. So, anyway, go for it. Don't let your fear of losing stop you from trying in any area of life.
