How do you get yourself to do a job you hate? Especially when you feel like you can't quit?

For some background, I am a SAHM, and my kids are both in school now. I have been working part time for the past 2 years. I am actually about to lose my job, which I am not too sad about to be honest. But I have to find a new job. I also have to help out more financially. I feel like I am in a good position to find a job I like, but in the meantime, I need to find a job to get by. It's hard for me to go out and apply for jobs, I feel like I am torturing myself when I am actually interviewing. I am hopeful for the future, but the present is hard.
