I'm not sure when it happened but nowadays every human emotion that goes beyond the usual (and therefore accepted) apathy is considered pathogenic and should be treated. Emotions are good, they are what makes us humans. And not all of them are about joy and happiness. But you should deal with them without medication on your own or with some help and support from your fellow members of the society if need be.
It starts already in early childhood when parents will do anything to prevent their kids from having contact with any even slightly negative emotion or experience. No wonder they fall apart at first failure that they encounter in real life. And it's a fact that there are more failures in life than successes. It's more, a path to success as paved with a series of failures. Their purpose is to learn from them, not to send us straight to psychiatrist.
Great post! Definitely a topic not talked about enough.
