Think of what it feels like to walk through a dark alley. You feel threatened and watching for any sounds or movements in the shadows or any noises behind you. The fear is designed to protect you. To keep you on the lookout. It's the same with social anxiety except it's threat to your self esteem, pride, ego, social standing etc. Next time you go out somewhere try to feel this threat detector is turned off even for a few seconds and you'll instantly feel a sense of relief as your sa evaporates. If you can manage to convince your mind to shut off this threat scanner you'll find this is the key to getting rid of social anxiety. So keep practicing turning off the threat scanner. You'll know you're on the right path as you'll feel very threatened to let your guard down but don't give in to that fear.
