This was me yesterday when B was trying to explain weighing different kinds of averages. Really, this is me when he tries to explain ANY mathematical or statistical concept. But when I'm not sleeping well and am stressed out (which is the norm lately), it's a million times worse.
I have had a lot of trouble with chronic illness in the last 5 years. My snarl of issues and diagnosis is what I'm going to call FADI: fibromyalgia, anxiety, depression, and insomnia. FADI causes me to struggle, but this weekend was a major win and a turning point towards a more normal pattern (at least for the next few months).
