Pre-Teen with Internet Addiction

Hi! My ten-year-old who is the sweetest girl on the planet is lying to us and spending 6-7 hours at night watching YouTube videos. We’ve banned her from all internet and computer use and then caught her coming into my office at night and doing it on my work computer. This morning when I caught her, she lied again about it. When I checked the history, she was on from midnight until 7am just watching YouTube videos. It’s clearly an addiction that she needs help with. I was hoping you guys know a coach who works with pre-teens with this type of struggle. I love her and I want to help her and it breaks my heart that she has this problem but the lying is triggering for me so I can’t deal with it without help from a professional. Thank you.
