One day, you don't feel like doing anything. Nothing interests you, everything bores you. Feel more and more empty inside, more and more dissatisfied with yourself and the world in general. Then even that feeling wears off, and you don't feel anything anymore. You become completely indifferent to what goes on around you... You forget how to laugh and cry - you're cold inside and incapable of loving anything or anyone... There's no going back... The disease has a name. It's called deadly tedium.
