Bold behavior might not be typical for you, but you recently took a brave step out of your comfort zone and you deserve credit for that. If you don't get the positive reinforcement you feel like you deserve from coworkers, seek it from the people you know will always be your cheerleaders: your friends. Share your story in a quick email and get a group conversation going about what you did. Sharing your experiences will help everyone get a better perspective and help you feel better.
