What a lovely thread Onewithwings.
Maybe I could share an experience with you from last year. I was walking every day for miles and miles as a distraction from thoughts of alcohol after first quitting. These were often laps of the city but on Sundays I would drive out to the Cotswolds countryside. I have several books of long circular walks that take you high into the hills.
Two months to the day after quitting drinking with the constant misery that it entails, I topped a forested hill and all of a sudden emerged into an open glade. There was a babbling brook across the trail illuminated by a bright shaft of sunlight. As I crossed it I suddenly thought - my goodness that's beautiful. The first surge of happiness out of the blue.
Was my this a sign from my HP or a clue that nature might well be my HP. I don't know but I remember it vividly to this day. I hope I can get back to that state of mind very soon. Hang in there and good luck!
