I heard an girl talk shit about me to her and my friends

Some of my friends aren’t talking to me now. And some girls I was friendly with, I want to go talk to the girl who was causing it because I think it’s through my facial tics , i want her to say it to my face but she keeps walking away from me when I approach her , I got her on her own two weeks ago but she didn’t talk to me or do it then. I don’t know how to do it without causing trouble ; I just want people to realise I can’t control it , I have an form of Tourette’s , I want to be happy at work but I can’t if she keeps talking shit about me , I heard her making fun of me and they was all laughing at me and not just that but my big false eyelashes too and she started mocking me and they was opposite me but not close enough for me to have it out with. I can’t always control my facial expressions, I have verbal and physical tics. I haven’t told anyone that only an customer. I think she thought I was looking at her weird to be an bitch , we used to talk small talk for an month then suddenly a few weeks ago she stopped talking to me and just looks at me and never stops watching me on the pole but she never claps. That’s the only thing I can think of. Unless it’s jealously because I’m really good on the pole and she doesn’t know any pole stuff maybe
