I have just calculated, and the current period of my angst cycle is about one month, 22 days, give or take about a week. The amplitude (intensity) of my cycle increases as the relationship goes on, until it culminates in the end.
This begs the question: is the rate of my angst dAngst/dt linear, or differential? That is to say, does the prolonged relationship cause the period to lengthen? Or the peak to rise?
More questions for later.
