I don't think I was feeling anxiety, more like amped up. I calmed down a lot after voting this morning.
Part of it is Election Day was a big deal to my parents (my father was naturalized, my mother has dual citizenship, so their focus was always more on the process of democracy, not the results). We kids were allowed to stay up as late as it took to call a winner (they were called faster then), and they would give each of us blank maps of the states with EV totals for each state so we could color in the states and add up the votes. My parents usually voted for opposing candidates--yet they maintained harmony and trust and love for each other.
