I haven't taken time to read the responses, so you might have heard this all before. I'm going to be as frank as I can here. Law school sucks. DO NOT go through this unless you really want to be a lawyer, and remember -- you will only make alot of money as a lawyer if you put all of your efforts into excelling in law school, which is hard to do if your heart's not in it. Honestly, I tell people that if they want to make money they should go to medical or business school. The legal profession is one of the least secure, in terms of your chances of becoming wealthy, successful, and happy. Especially if you're going to NYLS.
Most people with half a brain actually spend some time after college working somewhere, either gaining experience before law school or just taking a break. I did both, and I'm much happier now because of it. And my advice for dealing with your family? Seriously, tell them to go @#!* themselves. It's got to be done at some point with people like that, and the sooner the better. Get a job, have fun for at least a year or two, and then if you still want to become a lawyer go for it. That is, unless they're paying off all of your debt right away. If they want to pay for everything (living expenses, tuition, books, etc) then go for it.
