I am coming upon this thread a bit late, but I wanted to add what it is that I do when I can't seem to get calmed down.
I start out by noticing my breathing, moving in and out like the ebb and flow of the ocean tide. (I imagine the sound of the ebb and flow is the same as my rhythmic breath).
I imagine myself floating on the surface of the water, then I use a "mantra" that I learned from a hypnotherapist... "Nothing to think about, nothing to feel" and I repeat it slowly while focusing on my breathing.
After just a little while I am all calm and good to go. I can't say what your results may be as I have never shared these little techniques and tidbits with anyone else, but I hope that if you try it, it will work well for you!!
By the way, the walk sounds absolutely wonderful and I'd love to see pics.
Blessings,
Mark
