Peter, you need to focus on your own health now as you’re having an operation in two days time. You will be no good to Bridget if you don’t make a good recovery or make a slower recovery than you should have. Have you stocked up on food, toiletries, basic medication (eg Paracetamol or Ibuprofen) - and Laxatives in case they are needed?
Why not buy some postcards (and stamps), write a short note to Bridget on each and ask your daughter or a friend or neighbour to post one each day while you are recuperating. You could give the full set of cards to the person before your operation if you don’t want him/her to have to keep coming round.
