YellowEllis I think there is a balance that people are trying to find. One of the reasons I am being very open about the effect the illness has had on me is that people who are (understandably) sick of lockdown are rushing back to the shops, to attractions, to seeing friends and family, not realising that we do still really have to be cautious.
I don't think you will be reckless, either with your own safety or with other people's . However, you cannot count on other people being reckless with yours. So, it's possible to start getting out of the house, while still being very aware of trying to keep away from other people, avoid crowds, avoid close contact, and all the rest of it. I really don't think you need lock yourself away forever, you just need to be careful, and not just pretend (like some have) that it's "just the flu" and "we will be fine".
Think of strategies which will enable you to go out and still be reasonably safe. Have you bought cloth masks? You might think of also buying a clear face shield - there's lots of them on ebay, and even the ones marked as disposable can be reused again and again. They have to be used properly (eg wash hands before and after touching it) but they might help you to feel more secure. Have you thought of times of day (early in the morning, maybe) that you could go for a walk while avoiding people? Or lesser-used, wide roads?
