I've read the article, and while I obviously can't know exactly what he was going through at the time, if he quit a Benzo cold turkey, it is very likely he would experience withdrawal symptoms, which are quite awful and would fit what he is considering "agitated depression." But doctors don't know about the severity and possibility of withdrawal and have no real motivation (because it is so easy to just prescribe another drug) to learn about it. If you're suffering bad withdrawal, reinstating the drug might be the only thing in the short term that can take the agony away.

It is important that a counter-narrative to the "medication for life" narrative exists. Antidepressants cause serious side effects and withdrawal symptoms--while not delivering on their promise. This is a reality for some people, and I'm sorry if that upsets those who need to justify their personal choices by making them seem like the best choice for everyone.
