Psychological stress is the net effect of a condition that you are resisting or wish to escape, but the condition does not have any power in and of itself. Nothing has the power within itself to “create” stress. The loud music that raises the blood pressure of one person can be a source of delight to another. A divorce may be traumatic if it is unwanted, or a release into freedom if it is desired.
Like electricity, it’s just power. It can be used for good or ill. It’s a tool. So too is a condition, a person, an organization, etc. they can be used for positive or negative.
