My poor girl is so low already, they're really kicking her when she's down. 
She has had a lot of problems at school over the last couple of years really, but it's been much worse this last year and it's got rather nasty, with former friends ganging up on her and various people sending her (and her bf, who doesn't go to the school or even live in our city) really vile messages on social media and by text, ending with her refusing to go to school this summer. School have made some kind of effort to address the issues, mainly by talking to people. Everyone who sent messages etc just denied it was them and I was advised if we got any more like that to go to the police.
So eventually her attendance began to be a problem and school made a plan for her she initially went back on a reduced timetable and then was to go in full time. She went back for one whole day and the next day was sent home because someone in her year had covid. That was the end of the school year.
Things have been quiet up till now. She blocked everyone on social media and even got rid of some forms of it altogether. Today, a video has popped up on her tiktok, it's an ex friend of hers who has made a new account and it says on it, "Posing as the girl who slut shamed me right to my face" and she's making the same faces as my dd in some of her photos and then actually putting up the photos of my dd in the video. Dd says she hasn't done anything of the sort and doesn't even know when she last talked to this girl. It's just nasty and unnecessary but also not something threatening that you'd really go to the police with. My dd has reported the video but she says it's unlikely anything will happen about it. What it will do is stir up other people again because part of what happened before was that someone said dd had body shamed them, which she swore she hadn't, and the friends she did have left turned against her without even asking her about her version of events. Ironically dd says she gets called fat every day at school.
She's been in floods of tears and now she's saying she isn't going back, she can't do this for another year. I understand her feelings, I'm pretty sure if this were a job she'd be signed off with stress and I'm really worried about her. She attempted suicide already during the spring lockdown last year so I am very concerned.
At the same time, it's her GCSE year this year; she goes to a specialist school where the average school won't be doing most of her GCSE subjects and I'm just gutted to think that she might lose her education because of this because she is a really bright girl. I am beside myself with worry for her in all sorts of ways.
What on earth can I do? I really don't know what to do or where to get help with this. Any experience, or advice, please? I am about on my knees and so is she.
