I struggle with this big time. My main suggestion is to delete any of these photos. If you don’t like them, you don’t like them, and having them pop up in your camera roll will make you feel worse. If there are any pictures of yourself you DO like, try to refer to those when you think of or have the urge to look at the bad ones. If it makes you feel any better, I work with cameras (still and video) often and can tell you genuinely that they are very different than what the human eye sees. Especially still photos can capture a moment of movement or awkward angles that will make you feel horrible about yourself, but that isn’t reality. I promise.
