What can I do if my wife up and left 3 days ago, abandoning our house and taking our kids and all our pets out of the house without me knowing?

She didn’t let me say goodbye to my daughter or talking to me about it. I have tired numerous times to talk and see our daughter and she isn't allowing it saying if I come anywhere near them. She will get a PFA and call the cops. I have never abused them or hit them. But still won't let me see her. She is very depressed and has been since she's been off her meds for four years since our daughter was born and won't go back on them. I miss her so much and she isn't letting me see my daughter.
