Yess,I think there ARE things you can do. After some brutally awful holidays (so bad I even self harmed), I broke the season down and came up with a plan.

What do I want? What is realistic? What is likely? What is unlikely?
What can I do to make it work? What do I have little or no control of?
What would disappoint me? What would be a negative trigger?

So, what can I plan to avoid. What can I take a risk doing? What will I perhaps enjoy?

This helped me navigate my way through the season. I also communicated this to my family which surprisingly was entirely supportive.
