Crisis

A crisis (plural: crises) may occur on a personal or societal level. It may be a traumatic or stressful change in a person's life, or an unstable and dangerous social situation, in political, social, economic, military affairs, or a large-scale environmental event, especially one involving an impending abrupt change. More loosely, it is a term meaning 'a testing time' or 'emergency event'.

It's change, that's all.
