Try not to communicate with other people and just stick to your work and keep busy. Use your work habits to produce better and more efficient work.
When in a cult atmosphere, you will have to be somewhat two faced. Pretend your workplace is a stage and you MUST act. No need to put on the drama acting, but just play act by smiling and not speaking your mind.
You need this job for your own personal reasons, so just play act while at work so you fit in and can get the experience down on your resume before you move on.
Also, do not socialize with your co workers. If asked to do out of work activities by your co workers, let them know that your personal life is so full right now, that you don't have the time to socialize. If they ask further questions, just say you like to keep your personal life private.
Your job is a stage and you play act to get through the day. Just keep telling yourself that, this too, will pass.
