Lifesamerry, if your ds's difficulties are severe and blantly obvious, it will be easier. If your ds lashes out, is disruptive, causes others and teachers difficulties, it will be easier. It is expensive, im single parent, i begged, stole and borrowed and he still didnt get a statement, so im saving and preparing for round 2!
So unless you are exceptionally lucky, there will be anger, there will be tears for your own sanity you will learn to put your emotions on the back burner and treat it like a business arrangement and always be the calm, reasonable one. Rant on here if you need to, most of us have been in exactly the same position as you at some time or another, MN and all the wonderful support and understanding you will get, will be your life line.
And of course the reason you are doing all this, your ds, will give you the strength to fight, carry on and do whatever is necessary
