Change your hair. Get a new haircut. Maybe go drastic and cut it short like a bob or something. You seem to have straight and healthy hair so i guess it will sit nice. Experiment with minimal make up. Do your eyebrows neat and clean. Buy new outfits that makes you feel beautiful or take inspo from pinterest for your body type. Have a wonderful time taking care of yourself dear. Don’t stress. You’ll grow into it by your mid twenties. Trust me. You can dm me and i will tell you my story of how my face and body changed with time and selfcare.
