"Symptoms of narcissistic personality disorder and how severe they are can vary. People with the disorder can:

• Have an unreasonably high sense of self-importance and require constant, excessive admiration.
• Feel that they deserve privileges and special treatment.
• Expect to be recognized as superior even without achievements.
• Make achievements and talents seem bigger than they are.
• Be preoccupied with fantasies about success, power, brilliance, beauty or the perfect mate.
• Believe they are superior to others and can only spend time with or be understood by equally special people.
• Be critical of and look down on people they feel are not important.
• Expect special favors and expect other people to do what they want without questioning them.
• Take advantage of others to get what they want.
• Have an inability or unwillingness to recognize the needs and feelings of others.
• Be envious of others and believe others envy them.
• Behave in an arrogant way, brag a lot and come across as conceited.
• Insist on having the best of everything — for instance, the best car or office.
• At the same time, people with narcissistic personality disorder have trouble handling anything they view as criticism. They can:
• Become impatient or angry when they don’t receive special recognition or treatment.
• Have major problems interacting with others and easily feel slighted.
• React with rage or contempt and try to belittle other people to make themselves appear superior.
• Have difficulty managing their emotions and behavior.
• Experience major problems dealing with stress and adapting to change.
• Withdraw from or avoid situations in which they might fail.
• Feel depressed and moody because they fall short of perfection.
• Have secret feelings of insecurity, shame, humiliation and fear of being exposed as a failure."

I wish I’d never even heard the name ‘Trump’ but I feel like I know him well enough now that ‘all of the above’ feels accurate.
