Don't tell me you've never been jealous. It's normal to be jealous and in fact it's healthy to be jealous cause it gives us determination to do things a little harder in order to accomplish what others have that we don't have. This is why people, companies or nations want to strive harder whether it involves money, power, love, business, sports or just want an exposure or fame to become better than others, we live in a competitive world!
This behavior becomes detrimental when it reaches the extreme level and the person in that state of mind not being aware of it. Most people who experience severe jealousy never discuss it with their close friends or family members for anxiety of being humiliated so they rather keep it onto themselves. This lead to an accumulation of anger and frustrations inside to the point of emotional breakdown. If this person can't show it through physical violence, s/he will show it by threats and other means in retaliation to hurt the person who made them felt inferior or degraded including the person who they have an emotional attachment.
Here is one tip when you're in this situation, back up and evaluate yourself. You're not admitting a defeat but mending the psychological aspect while rejuvenating yourself into the positive person you should, to regain self-esteem, the lost energy and focus in rebuilding integrity, hope and confidence..instead of adding enemies.
