I rallied enough to do an LBRP and middle pillar. When I exited the temple room, My Gal asked if I was playing music. I said no. Her response was that it sounded like I had four people in the temple room with me. I take that as a good sign.
Pantheacon was transformational for me. I think part of this fatigue is my body adjusting to a new me. If that LBRP was indication, this may get fun.
