You might also check with the school that your DD attends. They sometimes have access to resources that can help. Or they might know of an individual that can assist you or open some doors that you otherwise wouldn't have known about.
You'll just have to get the word out that you need help....unfortunately it won't come knocking at your door. I know it's hard to even concentrate on things like this when you're feeling so badly. Possibly your DD's father could do some of the legwork for you since he doesn't want to actually participate in the "care" part of her life.
I just want to shake some sense into him....one day he'll regret not being there for her when she needs him.
