I'm in KY. I'm at a loss of what exactly I need to do...

So the mother of my two children tried to commit suicide by OD. I was told she took handfuls of pills while the kids was with her. The police came and stopped her and took her to a hospital. This is a dangerous environment for my children. For both mental and physical health. What do I need to file to protect my kids? I was told EPO from family court? But it was rejected! Do I need a ECO? Or something else I don't know about I need help. She's said before about crashing off the road to die with the kids! I don't want them to be hurt or find her with pills everywhere with no way to care for them self's or no way to contact help
