Oh goodness Aika. I'm sorry for my fast unsypathetic post.
Many of us here have been in the 'system' for a long time and we see a problem and know what the range of solutions might be, and post pretty bluntly and directly.
If you are anything like I was then right now you will be all over the place caught between despair, worry and trying to find ways to be optimistic, not to mention desperate to find ways to minimise the consequences of this new information for your dd.
To help you feel on top of this, in control and well, generally not so lost, I would recommend starting a log right now and a diary.
The log is to record every phone call, meeting, conversation, internet link that you come across, with the date, time, name of person/organisation, and contact details, puting a direct quote if you get one 'i.e. development specialist quoted waiting list 6 months' so that you can manage your journey and so that, should you need to, you can quote back to people their promises with the date and time. Internet links, books etc. can be simply recorded on the log for your attention when you have the time.
The diary doesn't have to be so organised, but is a dated list of behaviours/concerns/issues with your ds that at some point you think you'll want to seek help for, or just want to remind yourself about.
And, whilst I am a huge advocate of early intervention, please take a few weeks to just carry on as normal and do nice things, whilst you unconsciously get used to things.
