DD is sitting GCSEs this year. Non-communicative at the best of times, we discovered via GP who'd seen her because of daily headaches, lethargy and sleepless nights that she was behind with course work and had been since Xmas. Her reports had been good and we hadn't a clue. Blood tests reveal she is perfectly ok physically. She expressly doesn't want us to contact school and her form tutor has been absent for several weeks. She worked out a catch-up plan with said teachers and our help, but can't seem to cope with even bite sized chunks without slipping into an almost catatonic state - scary to see, eyes fluttering closed, head lolling back into sleep, completely out of it. Appetite remains good though. She's been sent home by the school nurse several afternoons recently and this morning, for the first time, refused to get up for school, although she did eventually. I've asked her form tutor to ring me today, but we don't know how to cope with this..
