Another vote for re-assessing this job and whether it is a good fit for you. I can vouch from personal experience that things that kill your soul have a huge effect from which it is sometimes difficult to bounce back. Many of these places count on your presumably youthful and abundant energy to ride to their dreams but by burning out, you may never be able to get to yours.

We all get one life in our current form and the challenge in this world, just like those standardized exams, is to figure out what is good/relevant and what is not - you are already ahead if you identified the not-good/irrelevant so toss it and go find something that is good for you instead. Edit: I would advise though that rebound is a thing so don't jump too hastily into a worse position - advice from trusted mentors is friends is what you need to either see the value in the current role and/or a future opportunity.
