A month of my life without any job

I was lucky to have found a job within two months after I came to Australia. It has become nearly three years living in Brisbane. During this time, I was never unemployed, always had regular income. The most jobs I had done until my last one were cleaning jobs. So I made up my mind to gain different experience in another industry. In other words, I got sick of it. I was hired as a courier driver in an Australian company. What intrigued me is to learn driving in Australia and have different experience in my resume. More importantly, I hoped that I would always communicate with customers and then improve my English. That was my plan. But it did not end up well, as I injured my back and spent too much in working and what's worse is that my salary expectation was considerably less. These factors caused me to chuck in the job. It has become nearly a month without job. Now I am in very desperate situation due to the fact that I am fed by my wife. I am the one who is supposed to provide my wife with food and clothing and other stuff. But at this moment, it is the other way around. I feel certain that it is not going to last long.
