No one here will be able to help locate your iPhone but yourself, and that would be done with Find My. Report your iPhone stolen along with the location to local law enforcement, but as stated do not try to retrieve it yourself, that can put your safety at risk. You should also turn on Lost Mode and report your iPhone stolen to your carrier.
By the way, you may get some messages claiming to be from “Apple” or “Apple Support,” but do not interact with those as that is the thief which is trying to get you to disable Activation Lock off your iPhone, making it fully usable to them.
But realistically, it’s unlikely that your iPhone will be recovered.
