Unhappiness feels threatening so we combat it with an arsenal of weapons. I think we would find it less threatening if we understood its evolutionary purpose.
Unhappy chemicals promote survival in the state of nature. If you are a hungry gazelle, you would rather be eating than running from a lion. Cortisol has to feel very bad to get you to do what it takes to save your life. It works! You can thank your cortisol for getting you to take action when necessary to meet your needs.
But cortisol didn't evolve for you to just sit there and be grateful for it. It evolved to give you the bad feeling that you will die if you don't "do something, now!" Your brain looks for ways to make the cortisol stop, and it chooses from the pathways it has. Your past successes at turning unhappy chemicals to happy chemicals carved pathways in your brain. Sometimes these pathways tempt you to mask your cortisol in ways that trigger even more cortisol. You would be better off doing nothing for a moment. But when you do nothing, it feel like you will die because your cortisol is doing the job it evolved for.
