Isn't it "Epinephrine"? Or is it "Epinepherine" also accepted? I wonder because English is my second language and many times I don't know scientific terms. Thank you.
You are unfortunately using a diluted, contemporary version of the term stress (psychological). When Hans Selye formulated it, and the general adaptation syndrome, stress encompassed anything that elicited a response in the organism. So for example, running, the flu, hunger, loud sounds, cold weather, burns are all stress.
I wondered about that too, because the cortisol is part of the Hypothalamic Pituitary Axis, which is a response to chronic stress (as opposed to the Sympathetic Adrenal Medullary pathway, which deals with an acute stressor). I wonder if maybe the adrenaline, which is part of the SAM is for fight/flight (very short-term) whilst the cortisol, which is part of the HPA, is for something more like a battle (i.e., short-ish-term). The cortisol acts as an anti-inflammatory, speeds wound healing, and boosts the immune system during the battle. This would all be part of phase one. However, if the stress continues for longer, the HPA isn't designed for this. In phase 2, the HPA starts to cause immuno-suppression instead, and the extra fuel which is being made available for battle, circulating in the bloodstream, starts to clog up blood vessels. The negative feedback loop, whereby cortisol levels tell the hypothalamus and pituitary gland to stop making cortisol, also gets 'broken' because it is overloaded. Not sure if that part happens in phase 2 or 3 though?
You explained in 4,5 minutes better than our lecturer in 1,5 hour... thank you!

Isn't the cortisol release in the 2nd phase?!
