I get through the holidays ANY WAY I CAN! LOL!
Seriously, I'm flexible! If it's going to be tough on me, I weasel out of it--if my family wants me there for pie and coffee, I show up for the coffee and conversation but pass on the pie. If I'm feeling strong and lean, I'll go for a holiday meal and stick with the lean/green choices and ice water.
As a last ditch effort to avoid without drawing lots of attention to myself, I fiddle around feeding my kids, cutting their food, filling drinks, and normally there is so much activity and noise, people don't notice that I never actually ate the mashed potatoes or rolls! LOL
Sometimes I have to be firmer than I like with my well-meaning mother. I am generally an easy-going person and am uncomfortable having to "put my foot down", so to speak, with my very meek (put persistent!) little mother.
You gotta do what you gotta do!
