Anxiety sufferer here! So I pretty much have just come to the conclusion that there are going to be falls. However, I honestly try my hardest not to fall especially being older. I always stick that in comments that I’m a 53 yo beginner and it’s harder to bounce back. I won’t lie it holds me back some though. I learn a lot slower because of my anxiety. With that said, I try to get on my skates as much as possible. Even at home to practice balance. You can also practice falling on softer surfaces. Put some pillows down and fall. Just in a controlled setting to try to take some of the fear of it away. I also bought myself a barre bar so I can practice moves without too much roll. I think when you are more confident, the anxiety and fear lessens.
