30 weeks pregnant, what to do with corona virus in the UK

So I have a low BMI and history of epilepsy, I’ve been classed as a high risk pregnancy because of this. I work for my partner’s company doing the admin side from home and my partner works on site with 40+ at one times.

I can self isolate for the 12 weeks but my partner has to go to work, if we don’t then we will loose everything. We won’t be able to pay out for rent on our house, his workshop or even get food. Money is so tight but we are really worried about catching the virus since we don’t know how it will effect the baby or pregnancy.

Can anyone give any advice? I’m getting so worried!
