This is a deep meta question; not the response you give others. When you ask yourself, “how do I feel,” is that answer you synthesize, the answer you draw from the edge of your conscious and unconscious self; is this answer a reference to the immediately preceding past of your inner experience, or is the answer from some self aware inner entity that exists in the ever changing experience of right now?
Reading How Emotions Are Made by Lisa Feldman Barret and A Liberated Mind by Steven Hayes will answer your question. More broadly, emotion construction theory and relational frame theory will answer your question.
Self awareness can be seen as set of relational frames. Relational frames are things like “equal” and “opposite”, “I” and “you”, “here” and “there”, “now” and “then” “more” and “less”… Each of relational frame (like “I”, “equal”, “here”, “now”) is like a Lego piece that you can combine with other relational frames (“I am here now”). Piece by piece, frame by frame, thought by thought, you build a sense of self! This is also roughly how feelings are built. Interestingly, your sense of self is not necessarily the same thing as self-awareness; people can believe all kinds of things about themselves and not be aware of them!
You can use self-awareness to examine emotions (e.g. “I notice that I am sad”). You can also create emotions based on your sense of self (e.g. “I failed, and therefore I am sad”). Sometimes, someone’s sense of self does not accept certain emotions (e.g. “Real men don’t cry”), and this rigid and skittish sense of self will do all kinds of things to escape self-awareness. One of therapy’s goals is to shine a light (the light of self-awareness) onto the sense of self, so that people can become psychologically flexible and resilient.
All of the above. In order to get a more accurate answer, I think it’s beneficial to compare superficial ego observation with what you have access to of your Self.
How do I feel?
Usually with my fingers :)
But more seriously, there are depths to how I feel. An easy example of this is how I feel in a moment vs how I feel about my life in general. There are also aspect of my life that I may be deeply unhappy about whilst feeling generally good about my life as a whole.
Especially over recent years, as relationships in my life have grown more complex, I’ve really started to appreciate how I can have two feelings about the same thing at the same time.
The only rational answer here is “how many fucking caps did you eat, man?”
My answer is “nope.”
