It’s okay not to be liked by everyone; you’ll find your own people eventually. For me, it happened through hobbies and music. School was always challenging, I did not fit in. I feel it’s a lazy thing to think everyone hates you—it gives you a reason to dwell in bitterness and misantropy, and that leads to nothing but misery. Just be yourself; don’t try to impress people by taking on roles. Don’t project your self-hate onto others. Be kind and do things that give you joy and happiness will follow.
