Hold on there as much as you can possibly tolerate. This toxic environment is indeed building up your personality and you will end up being a better professional (would you do those "intense study sessions" otherwise ?) and a better person (you are learning how to not treat people). Embrace those rotten attitudes and bitter words. Feel joy when you get them, for it is for a higher goal. Feel sad for them, for they are pretty much worthless human beings. Don't let them make you quit. Stay there, learn as much as you can and quit, with pride, when you feel those dumb asses have nothing to offer you anymore. And then, you win. They lose.
