Are there resources you could use inside the company? E.g. a coach/therapist? I think they'd be super-aware of the stresses of working in the business and honestly it's the closest fastest way of getting some support that I can think of.
Just talking it out on a regular basis with someone who knows the pressure. You're not the only one at that company feeling like that.
If you have (in the past) thought yourself smart and capable and liked, then you can find your way back to that with a bit of help.
Once you have a bit of a better emotional/skills platform and more resilience, then you can choose if you want to stay or go, and you'll find you've strengthened your position for new jobs. You might also find that your environment is pretty good, once you're more able to handle the pressure and BS that it comes with.
