Gabriellesca.it is so normal to be so scared!! I was absolutely petrified when I started and I assure you after you ride with them a while, you will become totally comfortable with them. My bike shop said to be prepared to fall off 11 times (who knows where THAT figure came from!!) I have fallen but I have gotten better and better and now don't even think about it. It DOES take time to become comfortable and what you are doing is right...practice, practice, practice. Plan to clip out a bit BEFORE you are ready to stop...plan ahead always and you will not fall. You will learn to go faster and you will learn to feel confident. It just takes TIME!! Good luck and don't give up!
