I think I understand why she told people not to look up her credits.
It seems this may be a case of "I am representative of everyone's experience."
Her first credit was in 2008 and then there is a 5 year gap between that and her next credit. Then 8 years between that one and the next.
For comparison, I pulled up the crew for The Boys. Most of them have tighter credits.
While there is probably some people in her situation. I feel that she also could have written this with the title: "I Work in Hollywood. Everyone Who Used to Make TV Is Now Waiting Tables."
And this isn't to disparage her. It was always a hard business and getting consistent work was always hard. Even if it is good.
