Hi

Your brother's behavior, marked by prolonged social withdrawal and severe irritability for years, seems to be consistent with chronic depression, social anxiety disorder, or mood dysregulation. A professional clinical assessment is highly recommended.

He would be needing an in person psychiatric consultation rather than asking in this forum multiple people who will all advise well, but with the above complaints it is best to consult directly and get assessed. Good luck

Hi, thanks for reaching out. Avoiding people, frequent anger and changes in the way someone communicates for 3–4 years shouldn’t simply be labelled as “bad behaviour”. Sometimes anger is just the visible layer; underneath there can be stress, anxiety, depression or unresolved emotional issues. Instead of repeatedly telling him to “behave properly”, try asking him what has been difficult for him lately. And yes, a psychological assessment would be helpful. Take therapy.
