How does being selfish could safe ourselves, or maybe how does it safes us from the pain that we never want it. Imagine yourself being left with nothing in this world and all you have is yourself, would you blame someone for the con·se·quences that we've made. knowing that there are days where you sacrifice so much for someone and they would run away in a blink of an eye, but at that point you choose to sacrifice  because of the feeling of loosing someone or something again and again, when that action is made and someone chooses to leave you, it doesn't mean that you didn't try enough, you've tried so hard and its their fault for not seeing that, dear you, its not worth it. Now you would feel extra worthless and seem like its a dead end towards your life or the life that you've created. Now look at yourself, and say i will be selfish , i would care for me and me only and nobody else. Gain that confident that you've lost, gain it back step firmly on your ground and say “ THIS IS MY HEALING TIME AND YOUR NOT GOING TO TAKE IT AWAY FROM ME” ignore bad people who lets you think otherwise. you need this now because you need to appreciate the things you have without thinking you need someone. Learn to be selfish, do things only that you think is right, out all negativity one side, ignore all things that will bring you harm, do things that you never thought you would before, be honest to your feelings, be as tough as you want, when you regained yourself, nobody would break you apart ever again.
