I think if you can stand up to a crowd then you are very brave not many people can do that (without feeling very very nervous, anyway) I cry everytime I watch gladiator or titanic, (they always crack me up) And get scared when I watch Aliens or something really scary..It's natural..Don't let people get to you, cos' they're just not worth it, the only thing worth something is you, believe in yourself cos' at the end of the day when you're fighting on that tennis court there's nobody else is gonna help you, that's what my dad used to say...And still says. Keep going the way you are and look up the best part is still to come I'm sure
