I know that it is difficult for many to make it through this time of year (myself included). Just know that you are not alone in your feelings, and that there is a brighter and better tomorrow. Take a deep breathe and take it one moment at a time. If being around relatives is difficult, just remember: YOU control how you feel. Do not give others that power. Do not allow yourself to fall into the trap of being reactive.
If you are alone (not by choice) try volunteering at a soup kitchen or shelter. You will be lifted by what your kindness can do for others.
I wish you all peace, love, and joy this holiday season.
