Hello there Sinking,
Just a quick word 'cause I'm in the middle of a batch of paperwork (!)
Sometimes I've found that if I pay too much attention to exactly how I'm feeling at every moment it can be counterproductive and I find myself worrying, "Oh, I'm feeling down. Don't know why. Omigod... what's happening," and so forth.
Whereas if I just sort of shut down my thoughts and go about my business for the day sometimes happiness will just come and settle on my shoulder like a butterfly.
May that happen with you. And your cat!
