Very few of my friends do not have children and grandchildren living abroad.
We are so lucky to have Whatsapp, Zoom, Googlemeet, etc so we can, not only speak to them, but have long face to face conversations online, whenever we want at no cost!
If your family are living in Europe, you should be able to afford an Easyjet flight for a visit.
More difficult if they are on the other side of the world but, if you can afford it and you are retired, make it a long visit. Someone I know whose family are in Australia reckons she has spent more time with her grandchildren than she might have done if they'd been in another part of the UK.
