The gender identity stuff (first started at 7 when most of her friends decided that they were trans - very definition of a social contagion. We moved because of this. Not an issue now), secret cell phone (given to her by her birth father. I am not her birth father, but have 100% raised her since 14 months - he's an insane loser drug addict), social media addiction (on secret cell phone - she had for ~4 months before we caught her on Tick Tock at 3am), terrible friend group (all flunking out of school, addicted to social media, gender identity, etc.), lying, bringing clothes in her backpack to change at school (because we don't allow her to dress like a sloot), mental health nonsense, and then the regular teenage stuff like lying, talking back, thinking she knows it all, breaking every house rule, procrastination, apathy, laziness, etc.
She's very intelligent and super athletic (won multiple BJJ NAGA tournaments before she refused to grapple anymore and now is a very good street hockey player), but chooses to surround herself with the lowest common denominator and has almost no drive. Everything comes easy to her, therefore she works at nothing. We are concerned what happens when she's out of our home as she'd do absolutely nothing productive if we allowed her to. A lot probably has to do with her birth father, who has been in and out of her life (due to rehab, suicide attempts, just disappearing) since I came into the picture.
That's probably more information than I should share to strangers, but there you go.
