Oh holy god, I feel for you. I used to work at a call center and it was Hell on Earth. The pressure, the demands that you be a precision machine instead of a human being, the draconian rules and punishment, and most of all, most horrible of all the things; the full and complete expectation that you should act happy and grateful for the abuse. Trust me when I say, that it is not just you. T-mobile was such a monstrous place that half of my team was on anti-depressants and anxiety drugs. I needed the money too, but I would suggest trying to find an alternative as soon as possible. Nothing is worth the degradation of that sort of environment.
Though there was one bright moment. Our team was the 'trail-blazers' and they once had one of their dumb contests to see who could decorate their section with their 'theme'. We festooned the place in flame patterns, burning stars, I created a 3-foot "Number One" sign that I covered in scenes of fire and monsters (small enough that you couldn't make them out from a distance) and in great big letters, the word "BURN". The managers, when they saw it, their faces... And in a lovely reversal, THEY were the ones who had to pretend that it was all great and that everything was wonderful...
So yes, please get out of there, it's extremely unhealthy for any person.
