Call your pediatrician to check for diabetes. Blood sugar changes can really make you crazy. But if she's not diabetic, then ask your pediatrician for a referral for a psychologist. Or just start calling a psychologist for an appointment tomorrow, .

Sugar crash may contribute, but she still needs professional help to learn to manage her anger.

It's not just "sugar crash." You are looking for excuses not to get her actual help.

Or justification for orthorexia

Maybe Dad does the same thing to get his way.

This sounds like a mental illness OP. I’d go to a psychiatrist- not a therapist. This is not anywhere in the realm of normal angry teenager. This is psychotic behavior, even if not happening all the time, this needs to be addressed by a medical professional, as in MD

*remorse not emotes….dang autocorrect

That means she is not really in control of her behaviors. She needs professional help to navigate other options for expressing herself, and support in using those options effectively.
I agree it could be related to sugar, but she still needs evaluation for glucose levels and mental health support. The emotes and shame are probably taking a toll on her.

No OP. Just no. Now I doubt it is 2% also. This isn't normal behavior. You know it. Help her.

I’m sorry but stealing car keys and locking you out of the house is more than just a “sugar crash.”

Of course. The question was when does this happen. And that is the answer. That is when it happens. Pretty much exclusively.

This isn't caused by "sugar crash" or "hormones."

What does happen sometimes is that the same mental health episodes that are causing her to exhibit erratic behaviors are also causing her to eat differently, e.g., binge eating or restriction.

I hope she doesn’t lock you out without your car keys or phone in extreme heat or cold.

This sounds a lot like my sister-in-law. I knew her back in HS before I got together with DH.

She started similarly to your DD, OP, but then she suffered a traumatic loss as an older teenager (roommate suicide) and a few other things happened and it escalated. She has been in inpatient and outpatient care at various points in her life but mostly rejects it until a crisis. Sometimes she is quite successful in her career but sometimes she rages at us or becomes threatening.

Her diagnosis is borderline personality disorder. I think she would have had the same problems regardless, but DH’s parents were in denial (at one point they wrote off a massive episode that included a cancelled family trip as “really hungry”) so I would be open-minded in your approach to getting help and seeking a medical diagnosis. And yes, mental health is part of a medical diagnosis.

Hugely remorseful.

Here is a clue - is she remorseful after? Or no memory of incident? Or rationalizes her behavior?
