I have an auto immune condition, receive 6 monthly disease modifying therapy for it. This affects me day to day and my immune system also. We have 3 children and I’m self employed. I host my mum and step father for Christmas every year - shop for it, cook it, etc etc. This year I’d like to go away with my husband and kids, and not host anyone. My step father is an alcoholic, my mum is an emotional wreck and will tell me I’ve ruined her Christmas and left her all alone. I am exhausted by them and my condition and would love the time with my husband and kids. AIBU?
