I figured it's all about loving yourself though. Like, I know it sounds cringe AF but it's so true. Nobody on this planet is like you - you're special. Nobody is perfect, but you have so many amazing traits and deserve all the happiness in the world.
What helps me is acknowledging I'm not going to be into everyone that's into me, and so it makes sense that not everyone I'm into is going to be into me. It's not personal, we just all have preferences, that's all. Remember, you are special. There are SO many people out there that will be just as into you as you are them - 'the 1' doesn't exist, there's a crazy amount of people out there just waiting to be discovered, I swear! You're amazing, one in 7.6 billion, and someone someday is going to make you so happy - just be patient, continue becoming the best version of yourself, and it'll happen when you least expect it. Trust me - you're beautiful.
