I burned out this winter. I didn't even mount the studded tires on the winter bike. I like bike commuting but the dread of riding a bike with heavy, slow tires in the dark both ways just weighed on me. I was just sick of the dark, sick of dealing with lights, sick of spending 10 minutes layering up, sick of riding a slow and heavy bike.
So I last rode December 3rd and didn't ride again until late March. And I have a lot more energy and a better outlook this spring.
If you need a break, take one. You will probably get back on the bike soon enough.
