When jealousy gets the best of you, it can cause you to think about things that you haven’t thought of before, therefore they are irrational. They can cause a person to act out, or go to serious lengths in order to seek revenge or prove a point. Jealousy can also cause one to “strut their stuff” or “throw themselves out to the world” to to make them look better than the person achieving more attention. I really hope this helps you!
