The real Camino

I have been feeling really fatigued since O'Cebriero and I feel that the constant grind of the Camino has finally caught up with me and I'm tired to the bone.
The last few 30km days have been 7 - 8 hour plus walks and you put two of them back to back and you will feel it in your body but put 30 of them back to back and it takes it toll.
For me this feels like saying goodbye to the past and the Camino itself with every step I take as I don't feel I will be back here again.
