Today was actually a pretty good day. I don't know if it was a sense of calm from having one more question answered, or if it was the face that it was the third day in a row of sunshine, but whatever it was, I was in a good mood practically all day, was focused and productive, and was in good spirits. I even went to dance class tonight (which I haven't done since I lost Dan), and while I'm stiff and sore, I'm still relatively content. I only lost it for a second at class, then was able to flow through it and keep going. I guess that's something.
At dance I was talking to one of the other students, and she said she knew of two other people whose husbands (I think they were both husbands) died of pneumonia, in circumstances that sound very similar to Dan's (very sudden onset, without many - if any - symptoms before). And my best friend talked to one of her co-workers who is a doctor and said it sounded like what I figured was correct. So that's also some solace. Or it may be just rationalizing, I don't know. But I'm not going to worry about it tonight, I'm going to hold on to the good feeling while it lasts, because I know there's probably more bad days ahead.
