I agree. I found that about 90% of my difficulties when dealing with crowds and people were not actually PCS but anxiety related. I am also being treated for anxiety and depression and this has made all the difference in social settings. The symptoms become a lot more bearable when one is less anxious about them. It is a vicious circle in some ways, because, indeed, anxiety is one of the symptoms of a head injury. I would recommend seeing someone to have the anxiety treated, if possible. It has helped me hugely and I feel like I have my life back again!
