The holidays are the busiest time for therapists as that is the hardest time for a lot of people. I have a hard time myself. The important thing to do is to do extra self care and find something you "can" do that is a positive, even if that means renting movies that are your favorites, planning on having a special meal for yourself and just making whatever holiday it is about self care and relaxing, light some candles, snuggle with a good book or a movie and eat something you like to eat.
