CPMPRBIDITY....it means “the simultaneous presence of two chronic diseases or conditions in a patient.”

They are not the same thing. They may occur simultaneously in certain people but one is not the other

The term “co-morbidity” describes two or more disorders or illnesses occurring in the same person. They can occur at the same time or one after the other. Co-morbidity also implies interactions between the illnesses that can worsen the course of both.

Establishing which came first or if one caused the other and why can be difficult

The term "co-morbid" has three definitions:

to indicate a medical condition existing simultaneously but independently with another condition in a patient (this is the older and more "correct" definition)

to indicate a medical condition in a patient that causes, is caused by, or is otherwise related to another condition in the same patient (this is a newer, non-standard definition and less well-accepted).

to indicate two or more medical conditions existing simultaneously regardless of their causal relationship

I can tell you from personal experience that being in very stressful, life threatening situations can cause all kinds of "abnormal" responses from individuals ranging from "heroic" to complete "meltdowns". Every person reacts differently. It's not an excuse for threatening someone but it is a very plausible explanation.
