My brother started a publishing house, and had lots of hopes for its success. Unfortunately he failed in his business. He is highly qualified and writes very good and sensible blogs. The problem is he keeps thinking that one of us, the family members have done something to contribute to his failure. He blames all of us for his failure, so much so that he has gone away leaving his family, even his wife and kids. his old mother as well as sister. He writes blogs and occasionally publishes a book. He is isolated, has no contact with us. I wonder if he has a psychological problem. Please help me understand my brother s behavior.
