Many of us have social anxiety, but don't even meet diagnostic criteria for something like social anxiety disorder. The reason our brain is wired like this is because these were actually adaptive survival mechanisms for usually our home environment. When you move out into the real world, and when you start to engage in work relationships, romantic relationships, even friendships, that life vest goes away. There's actually a process, everything from meditation to the DIY stuff to seeing a therapist or trying something like coaching that can unlearn some of these behaviors.
