In the recurrence of depression, your information-gathering system collates its intelligence and reports to you these facts: (1) there is nothing to do; (2) there is nowhere to go; (3) there is nothing to be; (4) there is no one to know. Without meaning-charged emotions keeping your brain on the straight and narrow, you would lose your balance and fall into an abyss of lucidity. And for a conscious being, lucidity is a cocktail without ingredients, a crystal clear concoction that will leave you hung over with reality. In perfect knowledge there is only perfect nothingness, which is perfectly painful if what you want is meaning in your life.
