staring problem

hi guys!! i just need some advice. i have a habit of staring at people without even noticing. i don’t mean to but it had gotten me in a lot of trouble that wouldn’t have happened if i didn’t have that habit. i’m not sure where it came from or why i do it, all i know is that when i’m stressed out and start to dissociate, i stare at random people. this includes one of my coworkers - who i have recently found out isn’t really friendly:( he basically just texted one of my friends to “tell that freak to stop looking at me” which kind of hurt,, really badly. so i need advice on how to stop this bad habit. thank you so so much !!!!!
