Haven't managed to get on between 4pm yesterday and now, so not sure what I've missed but don't have the energy to catch up! 
Thanks to tips on this thread I managed to get some prepping done yesterday, better late than never eh? I now have a completely full tin cupboard, other staples such as rice, pasta, ingredients to make bread. A full fridge, drinks fridge, and 2x half freezers. Also re-stocked (but not panic bought!) loo rolls, soap, anti-bac spray, bleach etc from the small selection that was left in the shop. Been picking up paracetamol, asprin (needed for my pregnancy) and/or calpol each time I've been in a shop since Monday so that's coming along nicely too.
I raised my concerns with travelling to work on public transport with my manager. Explained I know pregnant women are not known to be at any more of a risk at the moment, but that this had notched up my anxiety big time. Asked if I could wfh (something we are allowed to do regularly) or be given access to a parking space so that I could drive in. Was basically told to suck it up and get on with public transport.
Was up half the night in a rage (about several things, not just this), but on the plus side of that, the bathroom and kitchen have been scrubbed to within an inch of their life and I'm about to start on the bedrooms!
Just wanted to thank everyone for the advice I've had on here so far.
