First, acknowledge that you are upset, saddened, depressed, and/or lonely! It is alright to experience these emotions. These are normal human emotions, that every single person on the planet has experienced at some point in their lives. No one is happy all the time. No one is perfect, and life does not work that way.
Now that you have embraced the heavy emotion, release it! Don’t hold on to that negative energy. No need to let it consume your light and take over. Don’t let that emotion become you. And remember you are enough! Don’t let the expectation of throwing the best Christmas party, giving the perfect gift, or wearing the best festive outfit get in the way of your well desrved happiness. Just be you! You are enough and that is what is important. Not the stuff! The Holidays are about connecting with loved ones, the World, and the community around you. This brings me to my final tip.
Get out of your head and into the World!
