Not strictly a “daily” task but it’s a routine, mundane one; calling in sick. I have to speak directly to a manager and although I do not need to cite a reason, my childhood taught me to feel guilty about needing time for myself. The “daily-est” one that makes me anxious is brushing and flossing my teeth. When I was younger I didn’t take care of them and my gums bled and hurt a lot. My teeth still generally give me a huge amount of anxiety despite turning all that around over a decade ago.
