I can't find a job!

I have been searching for a job since college and now it has been 3 years and still I have found nothing! I am looking for jobs that range from no qualifications to more than I have out of desperation! I don't know what to do. I have had interviews and I have been close but never do I get chosen. I feel like if I get rejected one more time I might just loose my mind. The last rejection I got I cried for hours asking why I even bothered to go to college and wondering if I wasn't just the most worthless human on the planet. I need some suggestions or at least some support!

Most employers understand that a college graduate who accepts a job with no qualifications is going to be gone when the economy picks up. Try to fit the profile of a reliable person that will be there for many years to come.
