Do narcissists ever cheat themselves? Yes they do! They cheat themselves with the lie that they are better than you, they are flawless, unmatchable, unique, all powerful, deserving of reverence out of fear and admiration. They forget these qualities and this sort of a submission befits God only! They other thing they cheat themselves is that, they defeated you and crushed you, in contrast to the truth that you walked away utterly disgusted with the person he/she is! Keep moving ahead! Success is ahead! Never give up on yourself. Let them phatom your defeat and behave like they destroyed you. They can't so long as you keep your boundaries high and secure.
I only took a decision, and I own it. There’s nothing wrong about it. I simply decided to make myself happy because I’m responsible about it. I’m not responsible for other people’s happiness. Have no fear crossing that thin line in between you and the ones you love; and start making yourself happy first, then worry about them.
