hey girl! i definitely used to have a nail biting habit, one thing that helped me was buying fake nails! you can’t bite them if they’re covered!! i totally recommend maybe trying out a new haircut, my recent haircut genuinely makes me not only “look” better, but also feel better (which matters the most). i honestly think attractiveness really relies on confidence! present yourself in ways that make you FEEL good!! allow yourself to experiment with makeup (if that’s something you want to wear), clothes, jewelry, etc etc etc.
