NAIR BURNED MY VAG! HELP PLEASE 😭😭

So I was trying nair down there for the first time. I'm not allowed to use razors anymore for mental health reasons so my mom forced me to use it instead of shaving. I thought it'd be fine. I did everything right, followed all directions. But....i got a burn. And it's bad guys. I need some tips on what to do. I'm in so much pain please help!
