Stress is not just a mental state. There are real, physiological changes, such as rising cortisol levels. To say that it is just a "psychology dependent" situation is to say it is all in your head.

I didn't mean to imply mental problems, but emotion can trigger imbalances in how your system produce and regulate this molecules.

that's not psychology, that's neuroscience, and while generally observed, the phenomenon you describe isnt understood.

Stress isn't psychological? Think about what you are saying!

Strictly speaking, from a conventional mainstream scientific view, stress is physiological. Psychology is a subset of physiology (unless you believe minds are aphysical). The "stress" that you feel in your head when you're stressed is only part of a larger, bodywide physical response.

Only if you don't realize how psychology involves and implies biology.
