Everyone’s experience of all human emotions is the same: happiness, sadness, anger, etc, but jealousy feels different in each person. Some common emotions resulting from jealousy are hate, sadness, anger, or any combination of these and other emotions. The reason jealousy feels different to every person is that jealousy is NOT an emotion! This realization is the gateway to your ability to control and overcome jealousy: reject the knowledge and continue to suffer or accept it and learn to understand and master jealousy.
It will help here to distinguish between emotions and thoughts. Emotions are sensations, like happiness, anger, sadness, infatuation, anxiety, serenity, satisfaction, fear, hate, excitement, and embarrassment. When you “feel like a fool,” the emotional component is some mix of anger, embarrassment, and maybe sadness. The fool part of it is a thought: I realize that I’ve been tricked.
Similarly, jealousy is also a blend of many thoughts and emotions. Dissecting it will give you the understanding that you need to fight it, but be forewarned — it’s not easy getting that one sorted out!
