Your level of self-criticism is very low, so feelings such as shyness and inner discomfort are unfamiliar to you. And true it is- you make big efforts to feel confident. If anyone dares to make a remark to you, you do not take it as constructive criticism and immediately try to insult the offender. There may be people who aren´t a fans of your excessive narcissism but you don´t care about this and you choose to be in a circle of those people who praise you enough.
