In hindsight, that does sound performative af/maybe its a new angle to grift from her paypig simps? (...since they clearly aren't willing to pay for Nebula).
It's not like she has a real job. She could have cried prior to filming - got all the sad feelings out, took a lithum, than filmed the video essay. I thought she cried randomly during the video, than edited in an explanation subtitle onscreen. No one wants a long pause in the middle of a video essay to hear an off topic rant about a Youtuber's struggles with postpartum depression or whatever.
The man who made the exact same video as her 4 years ago, didn't pause to cry.
