Not the poster, but it's very familiar to me. I grew up in the midwest, and a friend from there says, "In the midwest we don't have bodies or feelings."
As a kid, I clearly remember having an epiphany: when people asked my how I was doing, they did not actually want to know how I was doing. There were a number of appropriate answers, "fine" first among them. If you watch the first 20 seconds of "How to Speak Minnesotan", it's this dynamic: https://www.youtube.com/watch?v=_-wx11l3nr4
The best way to convincingly say you're fine is to not know otherwise. So by my late teens I was very good at not knowing how I was feeling. After 20 years in California, I have unlearned a lot of this. Yoga especially helped, as at least with my instructor it was basically 90 minutes of learning to pay attention to the subtle feelings in my body. Unsurprisingly, paying attention to my emotional and physical health has a lot of benefits, so I am a much happier person and would never go back.
