I don’t think anything will help the author as much as giving a bunch of money away. I grew up in a community where I met good number of very rich people with inherited wealth and every one of them is depressed or has some other issue—hypochondria, feelings of inadequacy, or some strange striving for significance through conspicuous consumption which is, of course, ultimately unfulfilling, etc. The root cause in all these cases, in my view, is the money. Just give it away and face the fear of engaging with the world again.
