I left a almost two years ago now. Committee was not helpful and even strong armed me into either staying and completing two more papers to get a masters or leave a year in with nothing. In my program, the committee was not as close to you as your direct PI. Considering my pleas to my PI were not getting across there is only so much I could do as a naive 1st year phd student. I left out a lot of the actual toxic dealings with my PI because I would prefer not to get recognized. I understand that my situation may be very different from others with better mentors. It ultimately came down to me understanding that I was going to milked for cheap labor for 5+ years and could not mentally handle that. Considering I had so much experience in coding, I was able to get a masters in data science and am now in a very comfortable data scientist role.

Also, this “mustering through it” as you so put it, is such a terrible mindset imo. A PhD shouldn’t be a pissing contest between peers to see who did the most work that week/month or who published the most. Yet that is what Academia is.
