My "Dream Job" destroyed my life.

[Eyliana]

It sounds to me you have been doing a good job with trying to get the project somewhere. And that your boss has a clear image on how he wants it, but is not realistic about the way he wants to achieve it. And I don't think it means that you cannot do art as a living, because it is not the art part that is not working out, but the way of working. And I doubt that everybody in industry works like that. So, don't decide you are not made to be an artist based on a bad work experience.

And try to figure out if the trouble the job is causing on your well being is worth having the job.

On a bit more positive note; you have some experience, you have worked somewhere (even if it didn't work out), and you also know what to pay attention to for your next job.

I hope it helps a bit.
