Ok, not we have some clues to work with. If you are pressing the clutch all the way to the floor before it releases it could explain the tire spin and motion. Check for the following: 1. clutch plate warped or damaged 2. diaphragm springs fatigued or broken 3. leakage in hydraulic system 4. air trapped in hydraulic system 5. bad pilot bushing The bottom line is you may need a clutch replacement which is normal with age, miles and the way it's driven.
