I like this photo... it is a good illustration of upward and downward spirals... of contentment and sadness.
Sometimes, I need to "show" what I'm trying to say... because sometimes I can't point out what I'm feeling in words. And the numerical scales sort of suck. I saw one pain scale where "10" was expressed as, "Oh, dear, I'm feeling just dreadful"... I don't know anyone, other than me, who would actually say that to a doctor out loud, it sounds like a "British Stiff-Upper-Lip-ism".
But this works. I think I can figure out how to pinpoint from here and move on.
