I agree. Feels like the only reason she decided to respond to this person is to use it as an excuse to shill her new book to her readers and not out of genuine care for the other person.
"Hi Dan, thanks for calling the Suicide Helpline! I know what you're going through is tough. I went through what you're going through too, which I wrote all about in my new book, Suicide Kings, available on Amazon, buy now and get it 20% off the hardcover price for a limited time only! Here's an affiliate link, and an interview I did with the Today show. So yeah, I've been feeling down in the dumps lately too, and you know what I did? I wrote Suicide Kings, only $19.99 in two easy payments if you call 555-555-1513. That's 555-555-1513. Don't kill yourself Dan. I didn't. Write a book instead."
Reiterating something I wrote in another comment: the columnist's response is more than 2,300 words long. The mention of her book is 600 words in, is limited to a single sentence with no mention of what it's even about. And it is in the context of how the columnist fights feelings of inadequacy even during the ostensible high point of her career.
