I think a little break, let's say 4 full days, could be what you really need to charge you batteries again and return more efficient than before. At least that worked for me. Don't know if the more experienced member will agree with this "absolute deloading" approach, but I think it could really works wonders if you just burned out, both physically and mentally.
You will not lose anything, you will get your energy back.
I'm a noob though, so don't listen to me LOL
