IMO emotions are nothing complicated but just a sense of if something is good for me or bad for me-an appraisal, the welfare factor. I'm invited to a cocktail party. Awesome, great fun but wait Gladys will be there and I hate her." Two emotions playing out.

When I feel an unpleasant emotion I might do nothing or I might ask if this is something I need to confront and try to grow from or I might want to look at my own thinking for unrealistic irrational stuff. Things like exaggeration of the importance or telling myself this thing shouldn't be. Then I answer that unpleasant things and people do exist so do what you can with it and move on.

I know some people seem to think emotion is some big mystery as if they don't see the cause as if emotions just pop up from nowhere. That's their opinion also.
