>>24152643Serious talk for a minute, from my own experiences with women in somewhat similar public roles (content creators, streamers, models, etc.), the supportive comments don't really "help", in the sense that they can somehow serve as ersatz therapy and get someone over deepseated hangups.
Also, with vtubers there's another layer of abstraction (and thus self-doubt for the talent) that gets in between simply appreciating the comments. "You look amazing" for example doesn't mean much when a girl with self-confidence issues would easily, in her negative mindset, twist it into "you're just saying that about the AVATAR, you don't know the real ugly me...." (so it can be potentially even more harmful).
Of course, you could also just be talking about her other rl account, but even there, most of the photos are carefully curated and professionally made up. While she appreciates positive comments because she puts a lot of work into this (so she attributes the compliments more to her craftsmanship aspect if anything, than it helps her about her self-image issues with her natural beauty), from my experience dealing with women with similar hangups, these things don't get overcome if just enough hordes of random anonymous strangers on the internet tell them they look beautiful, but mostly because select people that are actually important to her in real life give her the reassurance and acceptance to become comfortable with her own body in everyday situations (so not just glamour shots, of which she'll always have a critical eye due to professional mindset anyway).
Also, especially with female streamers who have a large supportive fanbase (I don't want to say simps, but well yeah), there's also a habituation effect setting in. If everyone tells you everyday that you're perfect and we love you, it just becomes worthless background chatter that you're getting used to, take for granted, and has no effect anymore. You may have noticed and also gotten frustrated by the seemingly uncanny ability of streamers to pick the ONE negative comment out of ninetynine positive supportive comments, hyperfocus on that and go on a big unnecessary drama tirade about how NOBODY loves them or something other. That's part of that effect. When most people are praising you, the negative ones just stick out more, and that's what (you let) ruins your day more and you let live rent free in your head for larger and longer than they really deserve. It's irrational, but that's just how people (especially women, and especially public women in an entertainment field) are wired and it takes conscious effort to rewire that
sorry for the wallotexto, TLDR someone marry her and give her the actual irl affirmation she needs
