I hope everything is well in the end! You can't make a game if you don't have the will to do so. I believe that it's better to take longer than you planned, rather than push yourself to make something you can't do.
I've felt similar to this before. I think plenty of people have, too! I'm glad that you're taking a break. Whatever you do when you come back, I'll be very happy to be there to see it!
