Child Custody

I applied a case for divorce in sub court in the ground of mental cruelty, the was case started on Oct, 2016, for last two years i did not get any responds from my lawyers, only opposite lawyers dig me in the court and he was working for my opposite parties very well. So I was fed up then approach one of my relative and they took some money from money and only get decree of device, during the case my relative and lawyers always told me that you are only custody for your daughter. When I receive Order, it's completely favor for my opposite parties. in that Order they mention that child and mother separation is cruelty which is shocked me. Please advise me how to get child custody because my daughter suffer a lot and even not get proper food because of my ex wife mentally ill. if this continues my daughter can't survey her life and there is chance to go worse in health conditions. I went appeal but my lawyer is not move the case at all. this case is very special and we can easily win because I have medical certificate from NIMHANS which is strong evidence to get my child custody. my child is now 7 years old (girl child).
