How do i find a youtube channel

So I don't believe my friend fully (them being the one to tell me) BUT he said that some one aka my stalker/the one who doxes me so apparently they put my HOME ADDRESS in the video on THREE APPS tictoc, youtube, and maybe instagram and they most likely put my friends full legal name and home address there name is in their channels name so its (something something)shayla(something) and i would love help to find them so i can ask them politely to take the video/content done thank you!
