The symptoms or narcissism are numerous.

The most common symptoms of narcissism being:

•  A grandiose belief in being ‘unique’ and ‘special’.
•  An inflated and often pathological state of self (a ‘false self’), which is manufactured in order to receive approval and attention (narcissistic supply).
• A fine hair-line trigger in relation to any perceived criticism , which then brings on ‘narcissistic injury’ (insulting of the ego / false self)..
• An inability to be accountable or take responsibility for actions.
• Creating justifications and excuses that are pathological, unreasonable and extremely immature.
• Bi-polar like mood swings of depression (when not gaining attention and approval) and ‘high’s when feeling full of narcissistic supply.
• A profound lack of conscience and empathy, and an inability to assimilate how destructive actions impact on others.
• Limited resources to give to others in times of need for genuine reasons (other than soliciting narcissistic supply).
• Blaming of others (especially intimate partner) for feelings of inner pain, torment, shame and anger.
• An ability to manipulate, lie, charm, bully, threaten and deceive in order to get needs met.
• Envy, jealousy and rage towards other people who are happy and full of good feelings.
• Extreme discomfort, rage and distrust of others who take attention away.
• Extreme childish insecurities and blaming others for these insecurities.
• High levels of distrust towards intimate partners and certain others, and almost childish idealization of other individuals outside of intimate circles.
• An inability to follow through, complete tasks and dedicate oneself to any structure and conformity that doesn’t promote narcissistic supply.
• Pathological jealousy that cannot be reassured.
• Projection of own inadequacies onto others and twisting facts in order to create the other person (often the intimate partner) as the enemy.
• A parasitical approach to other people’s resources, believing they are entitled to take from this person or organization.
• A con-man demeanor that creates a spilt persona of ‘street angel / home devil’. (Most people who don’t know narcissists intimately think they’re wonderful people).
• An ability to severely discredit their intimate partners to other people.
• Attempting or enforcing the control and isolation of intimate partners.
