So a bit of back story. DD has ADHD/ASD, high functioning. She has had a lot of struggles with serious self harming, depression and anxiety.
She has been friends with (I'm going to call her Jane) Jane since they were 11yrs old. Jane has (I'm 100% sure) ADHD, untreated. Jane is a drama queen and launches from one drama to the next. She's had a tough time in the last few years as her parents divorced, her Mum left and is totally unreliable. There's a bunch of other stuff but too long to include. She doesn't get on well with her Dad but she is very loved.
Backstory over. Jane has in the last few months become suicidal. She has spent the last 5 weeks sending the most horrific messages at all hours to all her friends (and extended friends) saying that she is going to kill herself, she wants to end it, making plans, writing notes etc. Obviously all friends have been extremely worried.
Last week Jane, whilst on the phone to two friends, took an overdose.
Jane is now in a child and adolescent mental health facility. She went in willingly but now wants to leave but isn't being allowed to.
Surprisingly (in my mind) Jane still has her phone and is still, at all hours, sending these terrible messages to her friends.
I am very concerned about Jane, we all love her. BUT she is tearing dd apart. Her messages (some of which I have seen) are just dreadful and at the moment she is very angry and lashing out at everyone. Dh and I have seen a decline in dd's wellbeing, the return of some mental health issues, low mood and terrible insomnia.
The problem is that dd's friend is part of dd's core friendship group (of five, many of whom are getting fed up with Jane) and also dd's extended group of friends. They are all on group chats etc.
Dh and I have told dd to take a step back from her friend, not in 'our friendship is over way' but just a quiet step back, she needs to protect herself. The problem is the entanglement with other friends. She could leave the group chats but that means she misses out on everything else going on.
We just don't know how to advise her but are very concerned about the impact on dd who is very fragile at the moment.
Can anyone else suggest what to do?
