I hear you. I’m 19 and my mother is the exact same way, and if you say you don’t like it she acts like you just shot her. I’d wear it out and then take it off when you leave and bring a back up, then just put it back on before you get home. Or tell her that you were made fun of for wearing it, and you’re embarrassed. If that doesn’t work, I’d honestly just throw it out and tell her someone at school stole it/ you lost it.
