The dread of what might happen has passed. What might happen happened and now there is relief.
It is a common disappointment on a holiday with an alcoholic. The holidays intensify our reactions because we often have unrealistic hopes and expectations.
Take some deep breaths. You are not alone. This is a passage in your life,it is not permanent. Things will change, and you will meet those changes with courage and dignity.
Call the people you love tomorrow so they can help you remember you are important.
I hope you enjoy your little tree. Merry Christmas!
