[Healeys] clutch hydraulics question

Hi
First time on this forum and haven't got the foggiest idea what I'm doing.

I've taken out my Healey for the first time in two years. My problem is the
clutch is not functioning properly. I can let it out fully and, with pause,
the car will move forward or backward. seems the gas pedal is taking over
the clutch's function. Can I drive it to a garage or should I have it towed
?
