Hi op. This is a very different scenario to the one you posted in your op. Please get yourself on the eating disorders support thread, which is ongoing. I’ll post it below.
My dd has anorexia, as yet not diagnosed. She has lost a lot of weight and is an absolutely vile anorexic. This is normal. The body stops feeding the coretex and as a result, she has lost all empathy. She has been saying things like every day I wish you were dead, tells me all the time she hates me, that I am vile, has been violent to me etc. If you look at the thread I’m posting and read my comments and responses to them, you will get a flavour of the journey my dd is going on.
You need decent advice. The only thing that is important right now is that your dd eats. The referral to CAHMS is a good start but do be aware, diagnosis to advice and therapy can be long and we were given no support beyond take her to A&E if there are concerns.
My dd is being treated as if she has autism and PDA. We are paying privately for this with specialist eating disorder therapist but the therapist isn’t able to medically diagnose. I have spoken to the CAHMS psychiatrist and she was fine with the Ed counsellors approach.
Dh and I both have an hour with the therapist, dd also has an hour a week also. We have had to force dd to attend these meetings but they are bearing fruit. In the beginning she was eating 400/500 calories a day. Now she’s eating about 1400. Dd has also just taken her GCSEs. She only eats carrot sticks, humous, a little bit of cheese and grapes at home. Sometimes she will also eat sour cream and chive dip as well as tortilla chips. The ED specialist says that’s fine for the moment albeit far from ideal as she’s getting a reasonable amount of carb, protein and fat. I have sourced the highest calorie and protein of each of these products.
You have the added complexity that your dd is withdrawing from friends when mine has not. Please try not to get upset about how your dd is. If she is restricting and has for some time, she may be mentally ill and it’s the eating disorder talking. My dd is pretty mentally unwell. There are improvements but she still doesn’t see a problem with her eating albeit she now is able to eat.
We are also having to treat her like a year 5, ie about age 10.
