@Piiachu sounds like you could use with a good recharge. Good thing the holidays are here. Friends, family, good food, and perhaps a good book to read or movie to watch will help. Relaxing and getting your mind off of writing for a bit is actually where great ideas come from. I've done mini breaks in my writing to try and prevent myself from getting burnt out. But writing three book simotaniously can burn out most people.
So relax, enjoy your family and friends. It does a writer wonders.
