How do I fight a child abuse charge in Atlanta?

I need a lawyer to fight my child abuse charge against the Georgia child protective services. They took my 3 kids away 6 months ago because someone called and reported me for child abuse due to neglecting them. At the time I was struggling with my bipolar disorder and the doctors couldn’t get my medications right. I am back on track now and doing good, but no matter what I do or what information I give them, child protective services keeps telling me I’m not ready to have my kids back. My doctor will vouch for me that I am. How do I fight this child abuse case and get my children back home with me? I can prove I’m taking all my medications now as my doctor tells me to.
