I've had that same dilemma. I'm also a 'fabricoholic' ... was buying way more fabric than I was quilting. Because my stash is so large, I put myself on a 'no buy' diet this year. Shhhh, I wasn't completely successful.
But for some reason about 2 months ago, I was eager to to finish up a quilt, that got me making a few new ones that I've been wanting to make for a long time. Then I was sewing and quilting more than I had in a number of years.
Maybe step back, relax, find one quilt pattern / block that excites you and start on it. You might find yourself caught up in the joy of completing a top.
