Your downward spiral.

Your downward spiral can be very subtle or dramatic. Most people don’t understand when they have entered into their plunge into darkness and death. Contentment is the first step and foundation of spiralling up. Contentment is a state of peace through self-satisfaction. The self-satisfaction is what you give consent to, to receive your peace. When you have no contentment you fall through the trap door of boredom. And you’re spiralling into an entrapment of darkness.

Boredom is literally defined as being in a state of disinterest, weary, fatigue, indifferent, lethargic, monotony and tedium.
The feeling that nothing catches your interest, that everything's dull and flat.
