Do I have to take my daughter back to her mom

The short answer is "it depends."  There are many facts an attorney would have to evaluate to give you an answer to this question. You did not mention what your final order says about visititation and access. You also did not mention whether or not you even have an order. Another factor is the age of your daughter or who linked the suicide attempt to an abusive relationship with the mother. If your child is being abused by the mother and you can prove it, then you may be faced with choosing between conflicting court orders. You could be putting your daughter at risk in knowingly releasing her back into her mother's care or you could be violating a possession order. In short, this is a very complicated issue and one you will not be able to navigate this sucessfully without counsel. I suggest you make an appointment with an attorney as soon as possible.
