Legal battle for my Autistic daughter

Hi I am a single mother of two. I am currently in a legal battle for my custody of my daughter Alexandria (Cookie).  I have lost temporary custody of her due to me  not knowing how to properly defend my self in court against her abusive father. We left him when she was 2 yrs old and I made the mistake of moving closer to him so he could be in her life more. BIGGEST mistake ever! Due to  series of events I lost temporary custody and he has been using her as a means to get back at me for leaving him. I currently found out that he is abusing his current girlfriend in front of Alexandria and her half sister ( child he has with current girlfriend).  My daughter has told me about the abuse going on in her father's household and I was able to pull the police reports and show that he is still being abusive in his current relationship.  I HAVE TO GET HER BACK!! I do not want my daughter to grow up thinking that it is OK for men to put their hands on you just because he feels some type of way! I have always tried to protect her, but right now my hands are tied with this court case. The court case is at a stand still because  the GAL ( guardian ad litem) which is the court assigned lawyer for my daughter during this custody trial is refusing to do any more work until she is paid. The bill is $6000! I am on a payment plan of $50, but that will take forever. I do not want her in that type of environment for another year. Alexandria has autism spectrum disorder she is high functioning. She is the sweetest child you will every meet she is kind and caring and always helpful. She misses her little brother R.J. (Bubba).  She tells me all the time she wants to come back home but my hands are tired. Her father doesn't accept her for her disability he believes that she not that disabled and if he pushes her hard enough to be normal she can be cured of her autism. Since she been at her house she has lost weight she had stopped talking for a while and regressed horribly. We have been in court for almost two years and I'm ready to end it and win full custody of my child to protect her so she can grow up to be a healthy mentally stable and functioning adult. I'm asking you to look into your hearts and please donate anything you can. Our next court date is July 24, 2019. I have to have this money by then in order to continue the custody case. I am highly confident based on the evidence I  have provided I can win full custody, and God has blessed me with two amazing pro bono lawyers, but the judge will only go off the GAL's report and she will not investigate or write it until she is paid in full. So please every little bit helps , and all proceeds will go directly to paying the GAL fees . Thank you for your time and consideration.God bless!
