I'm really sorry you're going through this -- I know it's really hard, but learning what Christian's problem is will be so helpful to everyone in the long run -- it'll allow everyone to address whatever special needs he has.
I know I've mentioned this other places, but you are not alone. I know it feels that way and that you are trying to get through a lot, but there are others out there who know what you're going through. And I do promise, you can get through this! Christian is a very bright and special little boy and with a few learning techniques (and similar), everything will turn out just fine!!!!!!!!!!
Feel free to contact me if you need ANYTHING!!!!!
All the best,
Ilene
