Breaker for bathrooms started kicking out-nothing is plugged in outlets when we set immediately kicks out again- thoughts on what it could be

To rule out a bad breaker, turn off the main, open the panel, and remove the wire from the breaker. Close it all up and test again. If it's not the breaker, then it is likely one of the wall switches, light fixtures, exhaust fan or a bad outlet. You will probably have to find it by process of elimination, disconnecting one item at a time. Make sure you know the full scope of items that are on this circuit.

Okay, this sounds like fun. Are you confident in opening the breaker panel and removing the wire from the breaker? Make sure that the breaker is off when you do this. By removing the wire, we determine if the breaker is faulty. If the breaker still trips when there is no wire on it, then it is faulty and needs to be replaced. Now, if the breaker is good, then take an ohm meter and check the resistance between the disconnected wire and the neutral wire (white) for that circuit. You should have the settings on the meter to the highest resistance. You should read infinite resistance, if not, then it could be a faulty receptacle or light socket in the circuit. Sometimes the plastic in the device (socket or receptacle) can develop a carbon path that may or may not show on an ohm test. When 120 volts is applied it arcs and sometimes shorts out. Assuming that you have a low resistance you need to find the device that is faulty. If you have a high resistance, you will still need to find the fault. Reconnect the wire, and leave the breaker off, and you should remove a device on that circuit and by process of elimination, check the circuit one device at a time.
