2000 Ford Taurus • 150,000 miles

My car went dead going down the highway and now all it will do is click when I turn the key to try and crank it. The battery is fully charged and the head lights are bright. I have not found any blown fuses. It sounds like the starter is attempting to engage when I try to turn it over bit I am not sure because the motor does not do anything at all. A friend tried to turn the motor by hand but could not move it which it being a front wheel drive I don't know how you do that.
I am in desperate need of my car and at my wits end on what else to do. Does anyone have any suggestions.

Engine should turn by hand front or rear wheel does not matter. Suspect engine has locked up due to bearing failure
