My brother is over sensitive or I don't know what to call about his worries. He is very much worried about consequences of his deeds. He wants to be perfect and doesn't want to commit anything wrong. And with his such behaviour he keeps on thinking alot and make others also to think in his way. If anything happens which is not  correct according to him, he start typing something in his phone.  With his do's and don'ts, he is impacting his child and others as well. And on top of all, he is not ready to meet any doctor for consultation. Please suggest me how should I help him. Thanks in advance.
