I also have a relative on the covid wards in the local hospital. There are hundreds of people (excluding ICU) needing hospitalisation. I really don't think the risk is almost zero. I think if the OP is in tier 1 that is very different to being in tier 3 or high tier 2 area. In those areas, prevalence will be significant. I agree with not scaremongering, but the OP has put a lot into keeping themselves safe for 9 months so it clearly matters to them. Why take unnecessary risks with only weeks to go until they are vaccinated presumably?
You have to try to separate the actual numbers of people in wards to the actual risk the OP is facing, because you're completely mixing them up.
If there are 100 people in my local hospital having been in car accidents, that doesn't mean my chances of being in a car accident are automatically higher.
Now, if there are 100 people who were in accidents on the same stretch of road, then I can say that my risk of an accident is higher if I go on that stretch of road.
At the moment, one of the most risky behaviours you can engage in, in terms of getting covid, is going into hospital (ironically).
The OP is not going into hospital. She is taking one trip into town. The actual risk posed by doing that activity (not by covid as a whole) is almost zero. That doesn't mean she definitely won't get covid, but if she's going to worry about covid then she should worry about getting knocked down too because that's also a risk. The odds that she will be absolutely fine, that nothing will happen to her and she'll come home safe and well, are absolutely overwhelming. Millions upon millions of people do exactly that every day. It is not a risky activity. So making the OP think it is isn't sensible, because it's just not true.
