I have had an ill relative and had lots of tiredness, working hard as well. I find my most of my sessions I am almost falling asleep when I close my eyes..
Not sure if you are asking a question from that or just sharing?
I understand both of your feelings though and you have my sympathy. I hope your relative can find some rest and peace for a recovery.
I work at a warehouse and it burns the energy out. I still enjoy my sessions though. I use them to relax first, and to have fun second. I find if I fall asleep briefly, or am just on the edge of both worlds it is quite relaxing. Ultimately it seems rather energizing just to breathe deep and let yourself unwind.
The session doesn't always have to be directly pleasure alone, enjoy the relaxation while you can too!
And have a Merry Christmas too!
