Am i forced to be homeless... Because of some bad mistakes I have made.?

I have horrible credit. Horrible my score is 487. I have made some terrible choices in the past. I have paid some of credit cards off and the rest I have consolidated. I broke a lease because of a bad relationship I was in. I have no family to speak of. But I am in school full-time and I have had a job for the last six months. I FULLY aware that I am in no position to get a GREAT apartment. I just want something safe and in my price range. I have been sleeping wherever I could until I get up enough money for a down payment for rent. Which I saved a quite a bit. I am taking control over my stupidity but no one will rent to me. My job and academic success depends on my stability. I have tried roomates and most of them require a credit check and I still get denied. I know I have to pay for my actions am i forced to be homeless because of it. Is there any programs to help someone like me?
