I had that same fear and was getting turned down for quite awhile before I got a job. In the mean time while I was looking for other full time work I was posting advertisements on bulletin boards and asking people if they needed some lawn care or any other type of work done.
I got by with those temporary odd jobs until I landed a full time job. It took me probably 1,000 job applications and even applying again at the same job I applied for before until I landed the job.
Don't give up on looking for a job and keep sending in those resumes you're bound to have a call back soon and get a job.
