Assist a depressed brother

My brother lost his position as a tax manager last year, September, and has not found another job despite submitting numerous applications.

The situation is challenging for him as he no longer interacts with anyone and spends most of his time alone in the house, either sleeping or watching television. He rarely leaves the premises. He has also ceased attending the gym, which he had been using frequently.

I am deeply concerned about his situation.

I would appreciate your assistance in finding a solution to this situation, as I find it distressing to see him in this predicament.
