I finished Robinson's Home, which has a nice, sad, hopeful, sort of melancholy ending and headed off to bed.
Then I started thinking melancholy thoughts.
Then I started thinking melancholy thoughts about myself.
Then I felt really sad.
Then my stomach began aching and I felt a little nauseated, so I got up for lemonade and crackers.
I've managed to worry myself sick! (Unless I sicked myself worried, because some sort of cold is also going around.)
