Sounds like your few really rough sessions left you wiped I had that happen more than a few times in the "process" It all ebbs and flows, depending on our own energy, etc. just like our own energy does. I still remember the times, fondly, when I'd get home and almost fall asleep in my dinner (we're talking 6:00-7:00 in the evening) I was so wiped from a session and I just couldn't understand what had made me so tired. Do you work with your dreams? They may kick up to help now that you feel as you do at the moment.
