A new schedule asks your nervous system to adjust, and if your nervous system already knows what it's like for things to change suddenly and without warning, that adjustment doesn't always feel safe just because it's expected.

It is totally understandable to react with shock or unease to an unexpected event that you were not prepared for such as when a loved one gets seriously ill, or you are in a car accident. You may connect the word trauma to an experience like this. Other common events associated with the word trauma could be war, assault, or abuse. You would be correct in thinking that these things embody the word trauma, but it only represents a small percentage of what is actually experienced as traumatic in our lives.
