I think that wasn’t really revealed in the show.

During season 6 she is working on a film with director Justin Kenyon, and due to the workplace incident we see her struggle with PTSD on set as her costar does an unscripted scene. Afterwards we see Justin try to console Gina- he is partially successful, but you can see he is exhausted by having to placate her.

In a later conversation- Kelsey Jannings is chosen to direct fireflame. While having a conversation with Kenyon she asked about Gina- where he stated that he couldn’t recommend her for the role especially if there are a lot of stunts.

Later on we do see Gina in a billboard for fireflame as lead actress. However- and this is a big however- we don’t actually know how she is doing. We don’t know if she gets help, how well the movie did, etc. etc.

She is fine in the way that she continues to get work, because she is great on camera- but we don’t really see if she continually gets work. Just like how when Bojack ran away and they used AI to generate him in the movie, a similar situation could have happened with Gina- especially if she had a massive breakdown on or off set. And to further that- we have no actual way to tell if it’s actually Gina because it could be AI and she signed away her rights.

I assume that she is fine. But it’s honestly up to your interpretation, per the ending of the series.
