Likewise, I walked the Shikoku pilgrimage earlier this year and found it an amazing experience which I can't stop thinking about. My journal is here for anyone who's interested: https://henro.co/journal/
It was one of the best things I've ever done.
Returning to the real world, work was a bit of a struggle. The charity and spirit of giving and receiving was incredible.
