Just read several posts complaining about being alone. I know how you feel. We live in the south of England. My son lives in Orkney ( North of Scotland). Bill has one son in Leeds another with mental health problems. I have a sister who is a mere 150 miles away and who does her best. Bill's brother refuses to come and see him at all. So loneliness is normal.
So I am signed up for Share and Care and I am waiting for a young person to come and share our house in exchange for 10 hours caring each week. Not sure how we will all cope but it is worth a try.
I will let you know if it works.
