People run away from me like Im a monster

Ever since 1st grade, people ran away from me and didn't like me at all. People would see me minding my own business and walking and say "Look, it's (my name) let's go away.". I don't know why this happens, from away, people laugh at me like I'm a joke, up close, they'll scream and run away from terror like I'm a supervillain or something. One time, a girl screamed facing me and ran away. A dude came and said "Yo why you scaring her you punk" and pushed me hardly and I almost fell. Why the hell does this happen? What can I do to stop it? I don't think it's I smell bad or anything related to hygiene, I brush my teeth everyday and I put on cologne and deodorant. Plus, I've smelled bad people and I've never done anything like that.
