Thank you all for your replies :)
Apologies for not replying sooner, it's a bit hectic here to say the least as DDs illness & injury nicely coincided with us having building work done, so it's been another kind of hell managing both & Im too worn out to string a coherent sentence together a lot of the time plus I managed to blow some of out electrics with a steamer used for wallpaper stripping & had no wifi until it dried out 
I will try & answer some of your points/questions, but excuse me not replying individually, I'm too brain dead right now to hold names for long enough to reply, but will do my best
Thank you to those of you giving info on home tutoring - she hasn't had any yet, just a little homework, but it is now in the pipeline thanks to her CAHMS mentor, who has been a help, but upto 5 hours was mentioned, so it's good to know that they can up that to 15 if/when she can cope.
She has been in too much pain to cope with schooling, barely sleeps, plus she is on strong pain medication & she can't think straight as a result & this is making school work hellish for us both, she gets very upset that she can't manage things as easily as she usually can & just won't cut herself any slack at all, & being the closest to her, I of course get it in the neck with upset & hysterics, which makes my helping her focus very, very tough on us both as she usually ends up throwing herself around & making her injury worse :(
That said some of her teachers have been great, others not so much so & when she does have a clear moment & gets into doing work, I see her light up & we have her back again:) but the general feeling has been to let her get better & catch up later, which as things are, I wouldn't mind so much - but she is a very anxious perfectionist & panics about losing her places in the higher sets, so it's a lot easier said than done
I've not exactly been too impressed with her form teacher, though have found out recently she actually had 2 & the other has been fantastic at replying & sorting things out
I did end up contacting the school, her 2nd form teacher was a big help & yes the ATL score was inaccurate as it's an average.
I did try not to show DD her report, but unfortunately her friends were discussing getting them online & she kept asking for it, which I kind of expected from her as she prides herself on doing well & she also wanted to know she wouldn't be moving down any sets, which she worries a lot about as she thinks the lower sets are noisier & she suffers with SPD - which is crazy in current circumstances, but unfortunately what I expect from DD, hence why I was asking, preparing myself for what I knew was coming.
Ironically she was easily pacified over the subject she lacks confidence in, as she hasn't done much work at all in it at home. She freaked when she hit a topic she hadn't covered yet & got herself into such a state we had to leave it, this made it easy for me to get her to understand they had nothing to mark her on, so to lighten up & deal with it when she's better
She did freak out over another topic I hadn't preempted, because her grade hadn't gone up
she had put a lot of effort into a written piece for assessment, even working on it in the middle of the night when she couldn't sleep & because of her effort & treble checking herself, she thought she had done well, but the timing of the report had me thinking it couldn't possibly be included, but she was still so upset about it - thankfully that teacher has been fantastic, & I can see why he was a favourite of hers.
I asked if it was possible to have a couple of lines of feedback on this written work & he wrote a very long email explaining that it wasn't included in her report mark, but gave it a very high grade, so she was over the moon & this & the rest of what he wrote, plus form teacher explaining the ATL inaccuracy has meant she finally calmed down - phew!!!
She's now found something else to panic about instead
!!!
We don't know yet when she will be back at school, there no wheelchair access yet, plus her sensory processing & dizziness etc are far worse because she's inactive & not sleeping well. We've been badly let down by our local kids hospital, even our GP agrees, so many things have gone wrong there, starting off with her being sent away with minor sprain advice & my having to argue with the head doctor to get any follow up at all & follow ups seem to have misdiagnosed & not taken her medical condition into account when assessing her - I swear at least 3 of the ones we've seen had no clue what it was at all, DH was really angry at the implications that she's an only child, so we were mollycoddling her & she was milking it - she is in reality very tough & fiercely independent 
She does now have an appointment next week to see a recommended specialist at another health authority, so we will have a better idea after that, but it could well mean she needs surgery & with recovery & rehab, that could mean a few months more yet :( - though we are keeping our fingers crossed for a miracle of course
Hi Toasty :) yes I do remember you :) - our luck hasn't changed this year - fingers crossed it improves as its getting silly now
think they will be carting me off if there's much more !
