Advice for sharing work

This is so embarrassing to admit but I find myself super hesitant to share any photography online, for fear of being judged. I am in my 40s, have kids and a husband, live in the suburbs, a totally normal life and situation. I dont really have anything at stake. But I have this irrational concern that someone I know (some of the not-nice parents from youth sports, for example) will stumble across any account I make and, I dont know, laugh behind my back about it? I’m confident about the quality of my photography but I am trying to get better (technically sound but still seeking my own voice) and somehow that trying seems so uncool and awkward.

Anyway, I am open to any advice for getting over this and/or how to maintain my anonymity (like how to prevent my finstas from showing up as “people you may know.”)
