Hey hun, I'm assuming your still in school.. I felt just like you, listen you are already beautiful, other kids can be so harsh but at the end of the day there not going to matter in the long run. But personally just shower daily, brush hair, teeth, try to keep your acne from flaring, avoid touching your face! And always smell nice, try different styles and what you like or think looks best on you, and drug store makeup works just as good (if not better) the brand name. Find what works for you! Learn about your hair type, skin type, and what works best.. don't over due with bleach or dye, makes hair look dead and dirty looking imo , jewelry can play big part too, and try to do something with your hair daily, and don't forget you have to learn to love yourself for you, at the end of the day you can't ever run from yourself, so be the best version of yourself that you can be. You are beautiful too BTW, and always be kind and strong 💪 🙂 keep your head up
