J.S.
This won't help for this year, but if you're miserable with spending time with the family, don't do it. The Holidays are a particularly stressful and miserable time for many people. They're stressed about spending money for the Holidays, etc. We see our families all year 'round and things are great, but at the Holidays, things can get a bit rocky, particularly at Thanksgiving. We've been much happier to do a quiet Thanksgiving at home and limit our visits to a short one at Christmas and short visits throughout the year. My MIL (whom I love) always says that house guests are like fish...they go bad in 3 days. Best Wishes for a successful visit this time around!
