According to Psychology superiority complex and inferiority complex are part of the same pathology and sometimes go hand in hand. Superiority being a superficial disguise for inadequate queslities. You have to ask yourself if another person's criticism reinforces your own negative self perception. And then, do you fight back only to stop feeling inferior?

My Demon revokes any prayer
He's grown contempt for love and hope
He betrays trust, twists truth and fair
Indifference is his way to cope
Engulfing sound of sensations
He quells with voices of despair
And muse of short lived inspirations
Flees at the sight of his cold stare
~Moy Demon - Mihayeel Lermontov~
