I think there is a big difference between being vulnerable/opening up about those things we are all dealing with, and the "frailty performance art" that OP is talking about. Exemplified by that cringe-worthy viral video of celebrities singing "Imagine" from their multi-million dollar homes early on in the pandemic. It's OK to have troubles in your life and to express and address those troubles without shame. It's another thing entirely to humble-brag about your first world problems on Social Media purely for likes and validation. One is healthy and productive, the other is narcissistic.
