2000 Chrysler Concorde fuel tank

My fuel tank filler neck is loose where you put gas in the car. Unfortunately now, the entire neck is not visible in the fuel tank after driving for a while. I parked the car until I can get it fixed. Is the fuel tank straps broke or something that allowed the gas tank and filler neck to remain in place? Besides, it is screw holes where the filler neck should be connected to the car. I'm afraid to drive it because I think it might blow up. My car is in detroit and I stay in flint and I really want to rig it and drive my car home. What shoiuld I do and whats the main problem
