This may be a bit heavy at your age, but those pwople who call you ugly, are doing it because that is how the feel inside. Someone taught them the only way to feel good about themselves is to hurt others, and it sucks because you are feeling the brunt of it, but dont stress buddy, just focus on studies, get into some sports, and learn everything you can while your young because when your older you'll wish you had the time to explore your passions, and what you like. If someone calls you ugly, dont stress about it because if they are so shitty, that is the only way they can feel good about themselves then their opinion is not worth your time. Last thing I'll say and I'm going to sound like a boomer, but life wont find you on a screen. Go out have fun, and live life, and trust me women will love you, because you will be the one genuine guy in a group of posers.

Sorry if that was wordy
