The whole movement of happiness, unhappiness, happiness, unhappiness, could be called unhappiness. You're suffering because your state of mind is in flux, moving back and forth. The ego's happiness is really a form of suffering, because it cannot live without unhappiness.
Eckhart TolleTrue happiness is not related to external conditions but comes from the unconditioned.
Eckhart TolleThe reason why some people love to engage in dangerous activities, such as mountain climbing, car racing, and so on, although they may not be aware of it, is that it forces them into the Now - that intensely alive state that is free of time, free of problems, free of thinking, free of the burden of the personality.
