Disclaimer: My first race is in a week, still I have opinions.
First, have a long talk with your ego. Tell it that, based on circumstances, results may not be pretty, but things will improve. Then, do the races. If you think of them as workouts, you will probably be able to perform at a higher level than you ever could solo, or even a group training ride. And you'll learn. Tactics, pack riding in a competitive environment, bike handling, the whole deal. You can ride with the intent of being pack filler, and focus on the experience aspect. It is early in the season. When your conditioning starts to come on, you'll be way ahead. And maybe the other riders will start to recognize and remember you for the right reasons.
