Unfortunately I'm not in your area or I would go with you. But here are some possible ideas.
Perhaps reach out to neighbors
See if any malls in your area open early for indoor walkers. There would be lots of walkers there to make friends with and you would not be walking alone if you fell
Perhaps attend some local churches to find people in your age category to go out with. This is not instant but over time you would find people
I don't know your age but a senior center perhaps
I know a woman who has had a stroke and has serious balance problems. She does water walking and othervwater exercises at the local rec center. At first she went alone. But now she has friends, her own little cheering section and people offer to pick her up and drive her home
I hope thes ideas help. God bless!
