Groundhog has said somewhere On here that she is shielding and can't go for a walk, she is quite right.
Unless you have had this letter from the government you won't understand the restrictions. I have had one and it clearly states you can open a window, but not go out.
Now how stringent you take this advice is obviously personal, I am sitting and pottering in the back garden as we do not have close neighbours , but I'm not even venturing into front garden. I have taken the view that if they are identifying me as extremely vulnerable then the least I can do is try and stay out of hospital and using precious bed.
As for shopping, all 3 major supermarkets have text me to say they have been contacted by gov recognising me as needing a home delivery.
My husband cannot go out, he is in the next group below me, but my letter also advises anyone else living in house not to go out.
it's very hard, but necessary.
