What about spending the day doing something you really like to do - go to a movie, rent some movies, do crafts, read, get outside and go for a walk, spend some time with friends, play a game, etc, etc. I am sure you are sad about not having your mother around so not having a traditional Thanksgiving may be just what you need. Make your plans now and stick with the plan. It will take the pressure off about what to do with your day.
