I hate my job.

I hate everything about my job. I am sitting at my desk in tears. I've been applying for other jobs for the past month now with no success. I am thinking about taking 2 part time jobs just to get away from here. This job is not good for my mental health. I can't just up and quit because I have other responsibilities. Is there anyone else at a job that they hate right now? How do you all get through it?
