It could also have the opposite effect and make things a lot worse.My best advice is to get into as many uncomfortable situations as possible and you'll eventually realise its not so bad.
Which I what I said on the first page.
How about putting your self into more and more situations where you feel less comfortable, then the more you do it in theory the more you get used to it.
I have tried that and it sort of works, but at the same time it makes me feel even worse about it. Especially when I think back after the event and reflect on things that I could have said or done differently.
I don't know, I'm a bit better then I use to be a year ago but it's still quite bad.
