In situations such as when I am put on the spot and have to speak in front of an audience, presentations, taking a sip in front of people, making eye contact with people im uncomfortable with, and other random situations, my head shakes uncontrollably and my neck goes rock hard. This is my most severe anxiety symptom and its exacerbated by the fear of it happening. Im jacked and attractive yet I cant even approach a girl because what if midway through a conversation my head starts going crazy. I dont have much if any symptoms of anxiety or social anxiety apart from this head shaking bullshit. Has anyone experienced this or fixed it? Would stretching or fixing my posture help?
