Is anyone else hyper conscious of how much noise they make? Even in my own home where I live alone I want to be as quiet as possible, I'm not sure why though?

Same. My reason is I get very sound-sensitive when I have a headache. Even when I don’t have one, I prefer quiet. Also, Introvert, so difficult to think if it’s noisy …. and by noisy I mean the refrigerator is making ice. 🤨
I work with and around noisy machines all day. I prefer quiet at home, or at least music of my choosing. Sometimes I do things slower if it means making less of a ruckus.
