Thanksgiving blues

Usually Thanksgiving is a time for family. But for me, it is a time to remember how broken my family is. I really don't want to go anywhere for the holiday. Why can't we all just act like it is any other day? I want to see my mamaw but my step-grandpa makes me feel extremely uncomfortable. Even though that is the only thing keeping me from going, I am going to have to think of an excuse to get out of it. What's worse, telling her how I feel and leaving her other questions unanswered, or straight up lies? Maybe lying isn't such a bad thing in certain circumstances. Wish me luck.
