I live in a tier two coastal area, have invited adult son and his father, who live together, to stay in a local hotel and be in my house Xmas Eve and Xmas day. Also a very close friend who lives near me. My 87 mil lives with me but has her own living quarters and has chosen to be alone for Xmas. She hasn't yet been vaccinated. There is some shared air space in the house. My exh works NHS hospital including covid wards and hadn't yet been vaccinated or given lateral flow testing kit. He and son have both had covid at least once before ppe was adequate. Shall I go ahead with plans or cancel? The added dimension is that I'm grieving for DW who passed away in July and invited exh ( who is a good friend) and son in a panic not wanting to face Xmas alone, as it looked like my friend would be able to go to her family. I am now feeling emotionally and physically overwhelmed and wanted the pm to completely cancel Xmas. He didn't.
