Oh dear, I'm so sorry that you, greengran, and all those others of you feeling the same way, feel like life's coming to an end, but please believe me it's not.
When my grandson died I WANTED my life to come to an end. I felt as though I had let my son and his son down in some way. I even tried to end it (not the first time), but I even failed at that so had to face living again.
I won't pretend it's easy, but time is used up. Shopping is no longer a mad dash around the store, it's leisurely, and involves chatting to people.
A long walk every day takes up time, as do hobbies. Going out for the day is now an option, as are the month long holidays camping around Europe, catching up with friends, time in the garden, classes in things we always thought about but didn't have time for.........
Life at the moment isn't the reality, it's a pandemic! I'm guessing that the last one, a century ago, is remembered by very few, but in years to come we will all be talking about it, our great, great grandchildren, will learn about 2020 as a part of their history lessons, history that we are a part of. So no, this isn't life as it will be, this is history in the making!
