I am so sorry for all the terrible stress you are under, it sounds just awful.
Hugs if you want them. 
I know you have an appointment for your DD now, but was just wondering about something my DH and I tried.
I had all sorts of problems getting PTSD/OCD/depression sorted. Our GP told us the only way was with our local mental health unit, they were useless, and we can't keep paying privately as it is so expensive.
Anyway, DH looked up trauma treatments on the web and found that our local University has a treatment programme for sufferers of PTSD, they treat people and do research at the same time.
When we approached our GP they did not know the University ran any such trauma treatment, but they have finally agreed to fund me so that I can attend.
I know it's a long shot, but maybe your local University has a similar/ more relevant research programme for your DD.
They are researchers, so you have to be happy with that, and I haven't attended yet, but in the absence of little to nothing anything's worth a punt I think.
Again, I know it's a long shot, but I saw your thread and thought I should at least mention it.
Hope things improve soon and in the meantime try to make time to take good care of yourself. x
