I remember first trying to get into Katta's content. The "no-fucks-given" attitude was pretty interesting at first, but when your mental illness starts trumping everything interesting about your content, maybe it's time to actually start giving just a few fucks to improve your situation.
tl;dr Mental illness can be entertaining in the right dosages, but beyond a certain threshold, you just want the person to go and genuinely get help. This is why I can't watch someone like Tomoe Umari, she's too far gone in the depression spiral. The only person who really managed to make extreme mental illness top-tier entertainment is Pippa.
