Sorry this will be long :Dd aged aged 14 has got into a habit of staying up all night talking to her online friends and gaming. I have seen her online friends and know they are her age so that bit I am not worried about. This has been going on since the school holidays started. We switch the wifi off at about 3, but she then talks to them on her phone. Perhaps we were stupid to agree to this but after months of no school where she has only seen her school friends in person once we wanted her to have a chance to do what she wanted during the holidays. She has no interest in shopping or going out as she just wants to game. We agreed with her that she would gradually reset from this weekend so that she is in some sort of normal sleep pattern by Thursday when she returns to school.Neither DH nor I have felt completely comfortable with her staying up all night as shes increasingly become detached from the family given she is going to bed as we get up, waking up at about 4 in the afternoon and then not eating at 'normal' times but we work
full time at home so we have nothing else to offer her to do in the day (according to her). Gone af
Rethe days where she wants to day trips. However, we knew there was a time limit when things needed to return to normal.
But last night (or 1 this morning ) the whole situation came to a head. Dd announced that she wants to catch the train on Monday to visit one of these friends who lives an hour from us. We said no as we know nothing about the family or where she will be. She will be 15 in a few weeks but is anxious about everything.ie she refuses to go into our local town as there are 'too many people'. But suddenly she has planned out how to travel to the other side of London on 3 trains. She went berserk and said we were over protective and were bad parents etc.
Our feelings about her staying up all night , the fact we never see her (she doesnt even eat with us now) came up and we switched the wifi off at 1 and took her phone. I rarely check her phone these days as she hates it and we have spent alot of time talking about appropriate messages etc and never had issues. I did check it last night though and it was fine except where she was arranging this visit and slagging us off for not letting her go!
I went into her room to speak to her to try and explain we were just concerned about her travelling so far away during covid to a place she had never been when we dont know the people and she wont even get a bus alone to our local town. She was hyperventilating as she was so upset and said she didnt trust me and we were stifling and over protective. 2 years ago she was self harming and she bought up the fact that she didnt trust me because I had told her dad when she asked me not too. She said she has hated me since and will never trust me again. I said I felt I couldn't not share that with DH as I would want to know if it was the other way round. She also said she needs her online friends as they are the only people she can speak to and she would never tell me anything again. I found that whole time when she was self harming terrifying. Self harm was something I didnt understand and had no idea what to do..The school were useless so we got her referred to CAMHs who tested her for autism and she came out as having "traits '. We also paid for private counselling but she hated it so we cancelled. I strongly suspect she does have ASD and that her 'special interest' is gaming and this group of girls she has made friends with. She also said she thinks she has ADHD and that she doesnt feel normal and wants it be tested. She said she has no interest in normal term stuffand I compare her. I thought we had moved on since the self harming and put it behind us but she said last night she cant even look at photos of herself from that time and she feels like she is going back there but she won't talk to me about it as she doesnt trust me.
We left it as the wifi going off and went to bed but I have been awake since 5 thinking what to do next.
How do I get her to talk to me about her feelings ? How do I build the trust up again that she says has gone? 
Would you let her go to this friends? I could drive her there but it would take 4 hour
s seeing as I would have to drive there and back twice. I would only do this once I had 'met'the parents on a video call. I have met the friend on these calls several times including last night.
I just dont know where to start.
I think we are going to have a challenge returning to school as her social anxiety has escalated over the last 6 months. She keeps telling me 'everyone's stays up all night but my worry is the total lack of socialising in real life. Shes just obsessed with her online friends.
Sorry for the length.
