Peace, your post has had me in tears...purely for your kindness and understanding, thank you.
Not sure what/where ed unit that you refer?
please allow me to rant again....school organisation is so bad that drama dept arranged/agreed a 7.30am lesson on a monday, teacher didnt turn up, following week was bank holiday,10am arranged/agreed...teacher didnt turn up, so now...
DDs half term consists of bank holiday monday
Tuesday 9am - 8.30 pm drama rehearsal due to school timetable cock up
Wednesday- same this is also dds 16th birthday which she cancelled last week as she does not want to associate milestone birthday "with the shit that is going on" 
Thursday - 12 - 8.30pm offiicial gcse drama exam
My plan for Tuesday:
get dd to school for rehearsals
try to get gp appt to talk about dd (no idea if they will talk about her with me?0=)
Hope to get dd siigned off school so she just goes in for exams
Letter to exam officer with state of her health
anyone have any idea if she can be signed off?
