Having to cope with the loss of a partner and moving house is a heck of a lot to go through. You sound as though you’re trying to make the best of things but it must be very hard and I can completely understand you dreading Christmas. Would it be an idea to book into a hotel so you’re not on your own but don’t have to socialise if you don’t want to.
When it comes to making friends I think you have to go slowly and settle for just finding a few people to exchange a friendly word with or maybe drink a coffee with , at least to start with. Look for activities in your area and try them out, maybe look at opportunities to volunteer if your health allows it. It does take longer to make friends when you’re older but they can pop up in the most surprising places.
