Isolation is also normal for me apart from seeing a friend once or twice a fortnight and one son one month, the other son the next month.
It took a while to get used to. Now I enjoy it, I am busy with gardening, reading, online forums, puzzles, home decorating, art, music, cinema, baking, new recipes, repurposing/renovating bits of furniture, good TV, catch up TV, watch quizzes, lots of walking etc.
Time for people isolating to try something new? Knitting, crochet, papier mache, colouring, growing veg, creating greetings cards.....so many things to do.
I often learn subjects I haven't had time for before; the states of America, the countries of Africa, kings and queens of England, rivers of Europe, the ages of man etc, etc.
