People often find themselves lonely during the holidays. I'm not sure what it is, but I know I am. I just try to be thankful for my health and that I have family to spend it with. I know I am blessed.
As for bulimia that too is a lonely road to have to travel. I sincerly, honestly, and respectfully would encourage you to seek professional help. Bulimia has more to do with an emotional release than with weight. Hang in there!
