Very similar story to MrSlant so wanted to encourage you. DD is now 16. She was diagnosed with dcd/dyspraxia at 11 (though I'd been pushing since she was 6 as it was obvious; they ' didn't want to label her'
) despite non diagnosis I followed a lot of advice from the Dyspraxia association. We bought a book called Caged in Chaos which was very useful, written by a secondary school age girl with DCD with lots of tips.
DD had a really hard time socially in primary school. Bullying etc. It was hard. She was terribly disorganised and couldn't do any sports very well, but by 11 had discovered xcountry running which she could do well with her own unique slightly loose sided style 
We had timetables stuck on walls so she could remember things, warnings like pp about doing things, she had some fiddle toys and 'chewelry' as she was very mouthy and had a tendency to chew everything in sight for sensory reasons.
Her handwriting has always been awful. It was such a relief when her high school senco said that there's no point forcing children like this to try and perfect something that's not going to happen. It's what we have technology for. She uses a laptop all the time now and has use of it in her GCSEs which are starting in 2 weeks.
Friends wise she has been so much happier in high school, particularly since y9 when she really found her tribe. She has a lovely group now - they all call themselves the geeks and weirdos but they're absolutely brilliant kids. Still been some bullying but lessened as they've got older. Hoping that sixth form college will be another turning point.
She's doing fairly well academically. I'm so proud of all she's achieved in the midst of her chaotic brain and fumbly fingers and stumbly feet. She works really hard.
She still can't do most sports apart from running but she gives them a go. She's happy to banter with her mates about how bad she is, same with science where she keeps breaking the equipment (teacher very understanding!) It's a bit worrying as she wants to do biology and chemistry A Level!!
Just to reassure you really. These children can do so well despite their difficulties. It can make them stronger. It's so tough as well and so frustrating when the system doesn't take you seriously or seems to disregard their condition. You have to be that pushy parent again and again to make sure school are doing all they can.
But they can come through it.
And like the pp said, I can't imagine DD without DCD. She's scatty, crazy, loud, energetic, positive and confident. She's funny and such good company. I wouldn't take it from her for all the tea in China, though I would have taken all the bullying and misunderstanding and pain.
