FL Mary, Maybe it's time to look for a walking buddy? Any idea how to find one near you? In TX mine are "built in" other close by, retired neighbors or younger neighbors' kids when Mama needs a break from chaos in her RV or trailer.
Here in MN, I either arrange to meet up with friends, watch for a neighbor to walk by, or do a "walk along" with far away friends - we use the time to walk near our homes and chat on the phone. Started during Covid, and have kind of kept it going.
Also use my walking time to meditate and pray/think about friends and loved ones. Or, I will take off for a quick walk when I am "stuck" on a project - just let my mind wander and sometimes the solution or a new approach pops up.
Finally, my favorite walks are with my littles - to the local park, where they are allowed to lead the way - playground, running on the ball fields, hide'n'seek, or the local woods for tree climbing, nature hunts... less than a steady pace, but lots of fun.
Have you looked for a walking buddy?
