I delegate! We have a very large family with a lot of holiday parties...just for the family. I haven't even touched the friend's, work & school events. In my family we share duties like hosting, cooking and driving older family members. We also do trades. Babysitting for house organization/cleaning. Cooking for grocery shopping. We trade a lot! I also gift something to myself whether it's a massage, a day alone doing something I want to do, getting a housekeeper, buying myself something I really want but might be a bit expensive. I treat me!
I also just put all negativity aside associated with my disease and just enjoy the fluff and joy of the holidays. I basically ignore, IBD for a few weeks.
