That doesn't really match my experience of depression unless you somehow redefine all those terms to mean something else. It's hard to see where the libido is in someone who doesn't want to get out of bed, even to eat. Or in the case from the article, someone who feels like a piece of wood, and who paces the hospital like a Roomba. All effects of drugs are effects and they become side effects when they are undesirable. You used to be able to buy the same medication as either a decongestant and an appetite suppressant. In either case, the other effect is a side effect. On the other hand, if you took an antacid every day for your depression, and had no effect on it, for years, you might consider that it didn't work. However, the analysts didn't think that was possible to say about analysis.
