Hi ajisalone
I can most definitely say that you are not a nutcase and that theres nothing wrong with you. If this makes you feel better I hope that you know you're not alone. When I have been fighting self-esteem issues as a result of being pushed around by some pretty nasty people and feeling left out of my groups of friends I have developed a lot of the same anxieties too. I'm not afraid of large crowds like you would find in concerts but I typically don't like spending time with large groups of people and my low self-esteem and social anxiety gets me stuttering, especially when I'm faced with people who have caused me problems or if I'm threatened, or feeling judged. But like downandlonely says most people don't have the time or energy to make checklists in their minds about anyones imperfections or flaws. Recently Ive also find it helpful to concentrate on the close friends that you have so you don't have to worry about winning the approval of strangers or the haters. May you rest assured you are not alone here on PC
