I personally don't agree that it's the "worst" emotion there is. It's a feeling we have. All of us. If we label it as bad we fear it and it grows!

I believe most of the painful feelings we have stem from fear. Jealousy is fear too. It's fear (translated to anger) that you haven't got what others have, you can't have it. This then leads us to the recognition we feel less than the other, not as worthy (self esteem).

I think we really do need to accept it as it is. It is. We all feel it or have felt it. It's not bad or good. It just is.
