Bad credit student loans?

I have pretty bad credit and I got accepted to a university and am having trouble getting student loans I already got some grants and filled out a fasfa and got money from that so I'm halfway there from that part (tuition) but need money for living expenses and can't work cause my school hours will very day to day. Does any one know any good place to get a loan for 40 grand? Also I don't have a co-signer with good credit eather
