You have a few more days to enroll into a graduate program for Spring '08 and get an I-20 (Talk to kaplan as they may help you get an I-20).  If unable to do that, get married to one of your friends on F-1 so your visa could be amended to an F-2.  Ot the ultimate, get married to a US citizen (if you know one) and you're all set.

All success!!
