We recemtly had lots of problems with our 14 (nearly15) years old behaviour, the trigger was her phone usage. She has refused to do any chores at home for weeks if not months,,or to do any extra studying (they are revising for GCSEs), she has also refused to go on many family putings. Any time the phone was taken away she bacome angry and thrown isnsults at me.
I did try compromises, plans etc, nothing worked.
So as a result I have restricted tiktok for now and implemented a parent link on her phone. I told her once she start doing the few things I have asked her to and put some effort in learning she can have it back.
For 5 days she gaves me a silent treatment and goes to school.without her phone (she takes a bus, so it would be useful if she had a contact with us..of course I am.worried and probably that is why she delicided to leave it.
I am not sure what can be done at this point.
Never though we will have problems like that...
(she looks fine otherwise, has few friends, ok at school etc)
