Hello! It must be painful to see your brother in this situation and equally challenging for your brother to also cope through so much going on currently. Visiting a therapist would be better to understand him and what he has been experiencing. A therapist can definitely help in coping with this situation and in case it's necessary s/he may suggest a visit to a psychiatrist as well. I hope this helps. Thank You!

Hi... Depression needs to be treated first.  Still need history to specify further help. Consult a psychiatrist for complete help.  Brother can come out of his problem gradually if he has help.

Hi.. it's better to sit and talk to your brother regarding the facts. You can take the help of family members whom you confide in.

He need detailed evaluation for appropriate management.
