How catastrophes differ from major life changes?

Catastrophes are sudden, extreme events that cause widespread damage or distress, often beyond individuals' control, while major life changes are significant transitions or events that can have a more gradual or long-term impact on a person's life. Catastrophes typically involve loss or destruction on a large scale and can be traumatic, while major life changes may include positive or negative developments that impact a person's routine, relationships, and overall well-being.
