Everyone at school found out about my channel

I'm a high schooler who has a channel with over 100,000 subscribers (most recent video has almost 500k) I told a friend a while ago, and that brat told a bunch of people when I chose to stop being friends with her. They told more people and now everyone knows.

They continue to talk about it behind my back, and I just wish they would leave it alone and move on, I want nothing to do with them. It's a faceless channel, so it could be bad. What should I do? Please be nice

Edit: For those asking why it could be bad, it's cause my parents don't know about it. Don't worry, I never have posted anything offensive. It's a commentary channel, I have an amazing community. When I ended my friendship with the girl who I told, she contacted me through another friend and sent me a snap story of my channel, encouraging people to check out the "cringe channel by (...)". I begged her not to, and then blocked her (: So that's how everyone knows lol
