I can't pretend that I "understand" your situation b/c I am just not there. However, I strongly agree with Kurn and Drew. If I feel like I am going numb in the slightest bit I play something else at a very low level (Stud, OH, O8, Razz and HORSE). Being exposed to other dimensions of poker does shake things up.
Also, if you can float it, use some of that cash for a trip or other "I always wanted to do that" experience. Why not travel and visit your favourite TP members and try to beat their home games?
