Hi, I have a friend who is really timid, and antisocial. I have been talking to him for almost two years and he talks a little bit more about him now than before, but I think he can not express himself in a normal way, because he is timid, and he rather run away instead of facing people. the point is how can I help him to talk to me instead of run away? he is in his 30's and I think he has serious problems, how can I help him?
