In the long run, taping won't help. You need to condition your ankle to work well. It's probably got little to do with impact per se, and more to do with how you're running and the relative conditioning of your musculature.
Do proprioceptive exercises like balancing on one leg, hopping, etc. and body weight lunges, squats, etc. to ensure you've got good leg strength to enable stability and proper joint movement- imho poor leg musculature is the root cause of most non-trauma leg injuries.
Use google to find videos demonstrating how to do any exercises properly- doing them properly is more important than doing them poorly to maximise your reps.
Going to the doctor probably wouldn't have helped that much- an ankle injury is almost always a long term issue, and something you'll have to work out how to manage yourself, cos even with all the professionals in the world advising you, it'll come down to you doing something about it.
