Worried about teen DD. Will Beat help?

[Weightlossworried]

I'm becoming worried about my 15 yo. She's always been slim with a small appetite but lately she seems to have lost weight and is eating even less.
She denies any issues around food/body image when I've gently raised it. She hates school and for a long time has refused breakfast or to eat much or anything while there saying she feels too sick and anxious. She used to make up for it at home but doesn't really any more. She does always eat dinner and enjoys helping make it too.
I have no idea how much she weighs as we don't have scales and I don't think it would be helpful to weigh her but she is visibly thinner I believe, although she denies it.
I am pretty scared of saying or doing the wrong thing and making it worse. Can Beat offer help with this to parents? Thanks

Apparently when they start to ‘notice’ thoughts and say something like ‘I’ve noticed I’ve had a thought about x y z ‘ then they can try to separate by moving the thought into a category -eg. Calories, or restriction or guilt’ like putting it into a box in their head. The box is for ‘unhelpful’ thoughts. I’ve been listening to a therapy podcast about it and trying it with DD. Some of their thoughts might be ‘true’ so it’s unhelpful to dwell on if it’s true or not. Just if it’s unhelpful. (Eg a true thought could be -this meal has 600 calories that seems a lot)

might not work but I’m trying anything at the moment much like you we’re feeling quite stuck between wanting to get better and not wanting to get better. Sending strength today xx

That's really good advice, thank you. I think I have read that in a book too - I'm re-reading the Maudsley one again and that's got similar advice
