(((Hugs))), Butterfly. I completely understand finding the gratitude list hard to do. I carry around a little notebook (one of those decorative, pretty little mini notebooks) that I would jot down a gratitude for the day in. I started out trying to list 3 things that I was grateful for and 3 things I did well that day. I carried it around for 2 reasons: 1-I found that I was coming up with items throughout the day, but couldn't always remember it if I waited until the end of the day to write it down, and 2-it helped me back off from the negative self-talk.
At first, everything was centered around DS and I'd fill in the empty lines with stuff like Hawks mentioned (I have heat, power, wifi, I was able to stop for a mocha or latte
) It did get easier, though, as time went on to be able to come up with lists without 'filler' items. (Especially the 'I did good' list). You'll get there, too.
