Hi, My brother is currently in third year of engineering. Since he has been studying at a college in our hometown only. A few years back we noticed he had this insecurity feeling that he is not considered as a family member. His anger issues have also developed over a period of time now. Recently during lockdown he had mood swings but would still behave normal. But lately he has stopped talking to anyone in the family. He does talk to his friends but nothing else. I fear he is draining in to something wrong. How should we deal with him ?
