(please help) did i do the right thing?

i have a friend who's in middle school, she's 13 and tonight she was cyber-bullied. she was added in a group chat with a guy she knows from band and a random girl she doesn't know.

she got told the following things from the both of them:

i reported it anonymously to the school online. she never tells her parents (divorced) anything and when i told her she should tell the principal, she said she emailed the band teacher (they're close) and would rather discuss it with them but she downplays what happens to her a lot so i can't be sure what version of the story the band teacher got.

i am used to being a social pariah, so i've been around this block.

i'm scared that she'll hate me if she finds out but at the same time she never advocates for herself and what she was told by those bullies shouldn't be taken lightly.

did i do the right thing?

You already know you did the right thing.

Sometimes doing the right thing requires doing what is best for the person even if the person doesn't believe it's best for themself. They won't understand the seriousness at the given moment because their mind isn't in the right place, but they'll recognize it at a later point. Even if they don't end up appreciating it, they're safe from a brewing situation that could affect them later in life.

i know i did the right thing in general but i'm trying to let go of the doubt it was the right thing for her? like what if she gets bullied more bc i said something? i just want her to be happy.
