i mean it looks like any other autoimmune disorder, you just need to make sure you manage it as well as possible. doesn't look like her career is over at all, she just probably can't do aggressive promotion, touring, and travel, which in the social media/streaming/D2C age isn't much of an issue. she has a cult following that will be there regardless of if she hits their city for a concert or not.
in any case, i'm hoping this stays manageable for her and doesn't lead to worse ailments down the line.
