Stressed out about college, and not having a co-signer, what do i do!?

Hello, I am really stressed out right now, I am a freshman right now and I have to pay for college myself and will not have a co-signer for next school year. My school is no more than 18 grand a school year. What students loans are out there that will may for my tuition until i graduate without having a co-signer? I am on my own and really getting worried. I will need my whole entire tuition paid for until I graduate. I cant stop worrying about this because it is so important. I have to figure this out because I dont want to have to quit college just because I do not have a co-signer. i want an education. thanks for all the help
