Someone called DCF on me what do I do now?

I split with my ex and called DCF and reported to them that I am a junkie and a pill head and that my child is not safe. This allegation is untrue but what do they do now. I have moved a couple of times this year and having financial problems but my daughter always has had a room and been taken care of. This guy also went to my child's father and stated that I am doing things that I am not and he hired an attorney. I am not sure what happens now. I don't want to lose my child because I made a few moves.
