Well, in this awesome litigious country, you can take people to small claims court for ANYTHING.
But you are asking if you have a case or not. You do.
My suggestion is this: write a demand letter to your friend AND HER BOYFRIEND, asking them for reimbursement for your medical costs and medications. Inform them kindly in this letter that if they refuse, you will be forced to proceed with legal actions - in which you will sue for not only your medical bills, but for pain and suffering as well.
If that doesnt light a fire under their posteriors, then file a small claims action against them.
Take a look at lawschooltransparency.com. That'll give you a good idea about the school's job placement.
The odds aren't bad right now. Anywhere from 30-60% get into biglaw at most top schools. The better ones place more, of course. If you go to Stanford or Yale, the numbers will skew lower because many of them go into prestigious clerkships or academia. They're still great for biglaw, though, and they tend to get a very large number of interviews at OCI (on-campus interviews - a law school's internal recruiting process).
As I said in an answer to your previous question, you probably aren't going HYSC (Harvard, Yale, Stanford or Columbia) with your numbers unless you're URM (African American, Mexican American, Native American, Puerto Rican ancestry), attended one of a few select prestigious undergraduate universities or just have something crazy extraordinary, but you could get into NYU or UPenn. Those feed really well into the NYC legal market, which is doing fairly well. The job offers are nowhere near what they were before the crash, but better than Chicago, LA, and the secondary markets. If you can do median or better at NYU and you don't disqualify yourself at OCI by being a terrible interview, you will probably get some biglaw offer assuming you target New York. The going entry-level pay is around $160,000/year, although some pay more and some pay less. In NYC, that's not much. Your money goes a lot further in Chicago, parts of California, and secondary markets, of course.
