It got real bad for me this last winter and spring. Finally I decided I could die sitting scared on my couch or I could die enjoying life and getting better. I chose the latter. It hasn't been easy and there have been a few "oh ****" moments. All the same I'm happy I chose this path. Keep the wheels rolling Berta. When it looks impossible there is no shame in pulling over to regroup and take a break. It's ok to chop that hill up in a few short stretches or even walk up.
