Why is it that you think that you are so entitled to your feelings but other people are not? Do they not have the same feelings as you? Do they not feel from their experiences? Do you consider others not Worthy of a hire process of thought? Can they not also explore their past experiences or how they felt/feel?
Or just maybe it's " to protect your ego, likely to blame others for the disappointment, which reinforces your sense of entitlement."
Maybe it's something healthy, "Often individuals who have been mistreated or disrespected exhibit a sense of entitlement when they start to feel that they deserve better than they have been getting.".
But the why can't I have my entitlement I have gone through struggles and experience that I will not forget. I too am deserving to express myself. To show my pain, anger or whatever it may be that I'm feeling.
So you can f*** off!
