Sorry Knittingnovice, I live alone and have recently caught a virus which has caused labyrinthitis, a severe balance problem. I've had it a month now and sometimes can't drive, it's the loneliest and most vulnerable I've ever felt, even though my son is only an hour and a bit away. I don't have a friend nearby I could ring, both of my best friends are 350 miles away. In a dire emergency I could try a neighbour, but they weren't much cop when my roof blew off last year.
We just have to be our own best friend and be kind to ourselves. Spend your 'lone' time doing nice things for you, even as basic as doing a menu plan and shopping list, go to the market to shop for lovely fruit and veg, spoil yourself a bit. Sundays here there is a large market and it has a nice community feel, I often go just to be amongst people. Next time you know you won't be seeing anyone on Sunday, plan a walk and a coffee at the end of it, even a piece of cake. I take my dog to the beach every day, and once a month go to the local art gallery with him. Since I was widowed I've never been invited to Sunday lunch - I think I miss the family sunday lunch mayhem the most. Take care.
