No filter has ever fixed the way you talk to yourself after you put the phone down.

Editing the image changes what other people see for a few seconds. It does nothing to the voice that starts up the moment the screen goes dark, and that voice is the one you actually live with. The gap between the two can even widen with practice, because every improved photo quietly confirms that the unedited version needed improving.

Spend the energy on the inside instead for one week. When the commentary starts, answer it the way you would answer a friend saying the same thing about themselves. Also try posting one photo you have not touched.
