Stress is there because it has helped survival. Our biological evolution is still catching up to our societal and technological evolution, hence mechanisms previous beneficial are now often the opposite.
Some people are even addicted to stress. Our cells get used to the flood of delicious cortisol and adrenaline, and then become desensitized to it, hence needing more. The cells then respond by sending more and more “hey, send down more cortisol” messages to the brain, and the self-reinforcing cycle perpetuates.

"We think that addicts may react to emotional stress in the same way that their stress hormone system reacts to the metyrapone test," says Dr. Kreek. At the slightest provocation, CRF and other stress-related neurotransmitters pour out into the brain, producing unpleasant emotions that make the addict want to take drugs again, she suggests. Since life is filled with little provocations, addicts in withdrawal are constantly having their stress system activated, she concludes.
