The answer is that you probably have if you think about it. Everyone to a certain extent has anxiety. Many successful people even use it to their advantage. It is how you use it or deal with it. People have a way of presenting themselves to hide this but the reality is that most people will understand i am sure. It is knowing who you can trust enough to talk about it with and i would suggest that most true friends would listen. i know most of the people i have ever met can see my shyness or anxiety and are very sensitive to me and it doesnt really become an issue. Sometimes i initially turn down invitations to social events but sometimes when i do go, i end up enjoying myself and being glad i went. and sometimes i even notice people who seem like me. hesitant to talk and socialise so i feel for them and understand what we are both going through.
