I had a very productive day but had a very sudden mood shift later in the afternoon. I've just come out of a lot of isolating and went to a big party. Felt okay at first but then got feeling alienated and anxious and couldn't socialize much at all. Stayed even though I was uncomfortable but then just had to go. Calmer now and I have some insight into the sudden shift but I've never had such a sudden shift before. Was unsettling and disappointing after such a good morning. Tomorrow is a new chance though.
