What Is the Phobia Name for Fear of Change?

According to Phobia Source, the term metathesiophobia is used to describe fear of changes. It describes an irrational and undesirable fear of a future different from the status quo of present day.

People suffering from metathesiophobia do not want life to change in any way, and they do not want to have anything different than what they currently have. Change disrupts a person's comfort zone. This fear can lead to anxiety and panic attacks about the future. Some events that trigger metathesiophobia include a sudden death of a loved one, a divorce, a job change, moving to a new place or the loss of existing long-term friendships.
