Judging from your brothers situation, at least he cant be the real himself - his status quo even his family needs to hide... Although you dont report good news or bad news, you can avoid the old peoples worry, but at the same time, they also refuse each others love and support. This part is very important in the relationship. Why is this a place worthy of your consideration Fang. Your brother from a more successful person to no job, extremely strong self-esteem over the years, he must have a lot of heart knot, can not talk to others (or even relatives) and get solved, the outbreak of depression and his personality and recent pressure are related. As a family member, he should be given a relaxed atmosphere for his release and expression. Through acceptance, understanding and care, he can learn to meet his emotional needs, allow him to be himself, to be an ordinary person rather than someone else, so as to help him to re-establish the goal of life and find the meaning of life. This is what psychotherapy can give him, which is missing in his growth for various reasons.
