Have you ever had somebody telling you that they ''feel good" or "feel bad"? A great variant of that is when someone says "Not too bad"!. I get to hear that all the time. Of course, such utterings don't tell me anything. How bad is bad, or how good is good? And what on earth is "not too bad"?
Emotions are not just a handful of feelings. There are hundreds of feelings and distinctions that, when used wisely, communicate very well how people are feeling. In order to be understood and helped by a friend, partner, or therapist, you need to let the person know what kind of good or what kind of bad you are feeling.
