Aww nan 🥰 your dd is amazing as are you. I'm so pleased she's doing well and life is moving forward.
Tempers, you are now in this horrible limbo space where you know there's a major problem but you're not yet in the system properly 😕 it's a shit place to be but one where most of us have been.
I'm not sure you can do more than you are, keep going with giving her food and don't hesitate to take her back to a&e if you're worried. Your dd is absolutely not well enough for school/college so I would stop her going, she needs to be on complete bedrest.
I'd also say that school counselling at this point is at best pointless and at worst harmful so I wouldn't encourage that at all. The school counsellor was hopeless with my dd and knew absolutely nothing about anorexia, she actually made things worse 🤦♀️
Therapy isn't encouraged at this point anyway as their brains too starved and thinking too irrational. It's not dissimilar to looking after someone with dementia or other brain based disorder. In starvation mode the brain can lose up to 40% of its mass. The body takes all the fats and calories it needs from the brain and just leaves the basic impulses (breathing etc) alone.
The fruit for breakfast is pointless, could your dd be convinced that porridge is healthy for breakfast? I would make that with double cream and give it to her. I swear this saved my dds life.
What your dd needs is fats for brain recovery, lots of teens never need any therapy they just need to recover their weight and allow the brain chance to recover.
Double cream, butter, lard etc is your dds medicine.
