How do I earn trust back?

I feel really bad. I joined tiktok a few months ago. I loved watching them and then I started making them. Me and my kids have a close relationship. My son especially. He's always been a momma's boy. On my tik tok I talked about my kids but never said their names. I would ask for advice. I would give advice and use things I went through with my kids as examples and sometimes just tell stories of what happened with my kids or make funny videos. But I always kept my kids identities hidden and only has a few hundred followers and that's nothing on tik tok. Someone at my son's school found my tik tok and I know that because he came home in tears asking why I posted every private thing he ever told me it thing that happened to him on tik tok. I told him it was just something I was making for other parents, I didn't expect middle schoolers to watch it and he said I ruined his life and he's never talking to me again and cried in his room for 2 hours. My daughter is 7 so this didn't affect her the same way it affected her brother and I feel God awful. I don't want to lose our close bond.
