Wow xxlotsxx, I had to double check your username to check it wasn't one of my previous ones!!
My dd (9.5) is at the start of a camhs (they call it cyps) in our county. They also don't recognise pda but I have to say I've been really happy with the cyps appts so far.
My dd has had a full cognitive assessment, as there's quite a lot going on with her, she's likely dyslexic too and partly I'm hoping she's displaying pda traits because of severe frustration with learning difficulties she has.
Summer holidays have been better than last summer, mostly because we're abroad and she's able to be under the water in the pool most of the day which she loves, but we did have a meltdown on a boat yesterday which was awful. In the end she jumped in the sea in anger/panic but it calmed her down and seconds later "this is brilliant, thanks for hiring the boat!!"
for you all, it's a lonely, judged place a lit of the time.
I've found quite a few bits and bobs that help, I'll post again when I've more time
