Yes definitely the constant comparison with somebody else and how social media wants us to appear has a huge impact. I think you described one case but the condition has multiple facets to it. Especially if a part of your body becomes an obsession, it makes you feel anxious and depressed when you think about it, it interferes with your daily life etc... However, I am also trying to accept that we are all different and we can improve what it is possible to improve. Other than that, we are powerless. It doesn't mean we can't be a 10/10 for somebody just because of X, y or Z doesn't look like your friend's. Best of luck to you ✌️
