Good for you that you learned to be selfish right away. Because, you know what? I am also a generous one. But learning how life work while struggling Puberty, i learned to be selfish as well just recently. In the past years, i choose other people and choose to be kind even if they are the people who cause my mental health. I experienced a lot from them to the point that I don’t love my self anymore. But now, I learned to choose myself. I just wish that I am like you. Knowing how to build a wall or being selfish when you already knew that it will damage your mental health. Because, I just can’t stand other people yearning for help. But those people I helped are ungrateful so i think, my generous side is just limited for those people who really needed my help now—I learn that i will just give it to the right people who know how to grateful for people who give them helps.
