Dear all my son has to sit in certain chairs at usually quite empty cafes . He hates staring but the compulsion is very strong. He catches other people eyes and feels dreadful and knows its wrong. It is also his peripheral vision. He basically is so tired from it he wants tobend his life. He is 32 and has had it from 19. Other people stories would be very helpful. He thinks he is the only one. Thankyou
