I'm sure it seems very stressful for him, but he needs to mentally step back and get it all into perspective. He has his family, he's earned enough to be comfortable in his remaining years, undoubtedly has friends who care for him. All this is, or once would have been, yesterday's chip-paper. He should try to avoid media exposure and get into something that really interests him, and which can hold his concentration, at least until he feels the low period in his life is finally in the past.
