 Narcissus are embedded in envy, jealousy and this soon turns into hatred. They are uncomfortable with the thought of your accomplishments or any progression in your life. They hold a mask of being cool, calm and collected when really they feel infuriated. They pretend to be fine with you achieving your goals in life but deep down they are not happy about it. The thought of your success is deeply painful for them. It becomes a reminder for where they did not succeed or did not obtain. The reason for this is because they are not happy with their own lives. Maybe they didn't get to achieve something that they wanted to achieve and you then become a reflection of everything they are not. They cause these things to happen to themselves. They constantly underestimate people and take them for granted. Their lives revolve around hating other people rather than doing something with their own lives. When they see that you have achieved something they keep the mask of being happy for you but beneath the surface they can't stand it because of this they take everything the wrong way. They take everything personally. They are very insecure and they have an inferiority complex. It triggers their hate, anger and envy and this is their motive for the abuse. It overrides any limited empathy or consideration for you. They have reptilian brains. Often their abuse is impulsive. Sometimes it can be calculated. Narcissists are often called pathological which means they are a combination of impulsive and compulsive behaviors. I think the important thing to remember is if someone is really happy and in harmony with themselves they would never feel a need to abuse or manipulate another person. Just let that sink in. Because that's the real truth here. Narcissists are broken inside. This is why they will act out in this way. Always having to one up you. Always having to abuse and manipulate you. Always having to one up you. Always having to one up you. Always having to one up you. Always having to abuse and manipulate you. It's important to remember that this stems from their own insecurities and instead of focusing on fixing them they would rather ignore them and distract themselves by focusing on yours instead. They will exaggerate your mistakes and minimize your accomplishments. They exaggerate their accomplishments and minimize their mistakes.
