You've got a lot going on, first the holidays, second the new house. Worrying about a quilt you are behind on is probably a third stressor. It's natural to avoid stressful things!
I think the advice to start small is good. try picking one thing, dividing it up into bite-size (doable chunks) and then doing the first chunk, may break the logjam there and get you back in the swing.
Good luck! And congratulations on your new home!
