Try to get busy with something. I just pushed back from the Easter lunch table with my kids and my STBXW. The feelings I have toward my STBXW right now make it VERY difficult to be in the same house with her, let alone in the same room sharing a meal with her on what should be a happy family day. So, I understand the holiday "trigger."
How about starting a new book or going for a long walk (might be a bit too cold fir that) or clean the house. Anything to get your mind off the other stuff.
