One thing you can consider (in the US): quit and file for unemployment benefits - it's a hostile work environment, so youre entitled to this. That would give you some cushion while searching for a new job.
To qualify for unemployment, you must be out of work through no fault of your own. If you quit your job voluntarily, without good cause, you won't be eligible for unemployment benefits. However, if you are forced out and/or have good cause to quit, you may still be eligible for benefits, depending on the circumstances.
