About a month ago, close to her twelth birthday dd told her dad (we're divorced) that she has been purging. She had been having problems at school for a little while, having started secondary during covid and not liking the new schools rules or making friends. Up until Christmas she seemed her normal self but since then seems to have generally been a downward spiral. Dad took her to the GP who checked her bmi - normal - and did bloods - at that point ok. Did a referral to CAMHS which was turned down. Since then she has pretty much stopped eating altogether and the very small amount she does eat she brings back up. We went to a&e on tues where they checked bp (ok) and got her to eat half a sandwich but didn't do bloods. Referred back to GP who has given appt on 13/8 to consider re-referral. She is now refusing pretty much all food, is purging the little she does eat and can't have eaten the volume of a single normal meal since Tues (at which point she hadn't eaten for a week). I'm beside myself. What do I do except as calmly as I can keep presenting food and asking her to eat it? Should I just go back to A&E tonight? It feels like an emergency but I have no comparators except for earlier this week which the gp seemed to think could wait given when the appt is.
