Want to quit my job

I want to quit my job. I'm so miserable! But I can't afford to leave but getting a new job isn't so easy here! My manager is horrible, the hours are long and stupid. I hardly get family time anymore. I've never felt so low in my life. Been trying to find a new Job but still no success. I've got two weeks off and the thought of going back makes me sick I miss my family and being off has made me realise how much I miss it.
