I can relate with this, I had that experience many times and trust me I know a bit of how it feels. It's not funny knowing fully that you are capable of doing something only to get the opportunity and then all the courage in you suddenly fails you.
It's something you can work on by constantly doing the things you feel scared to do. Face the crowd even if you don't get the expected results, repeat the process. Don't hold yourself back, believe in yourself, dare things, take responsibilities that seems to always scare you away, it might be of help.
Thanks for sharing my boss
