There are some fallacious statements in your initial post, like that 98% of people are hired guaranteed. Past statistics do not guarantee future ones. And when you factor in that more and more hospitals are forcing BSNs on ADN nurses and not hiring ADN ones at all, walking in as a diploma nurse is a death sentence. I had a co-worker who was a diploma nurse, and she worked at an urgent care clinic for five years because no hospital would take her. So you might get a job, but it might be doing paperwork. Do you really want to limit yourself there? And if you don't find a job, what are they going to do? Hold a place hostage until it hires however many other students to reach their 98% quota?
Also, there's the problem of how you chose nursing. You gave yourself three choices and eliminated two. There are more than three choices in life. And fear of having a hard time getting a job shouldn't be the only driving factor (and is especially ironic if you're considering going into a diploma program, where you will have trouble finding a job, I'm willing to bet). I was the type of person that listened to my parents all the time, too, and at 24, I have already acquired a massive amount of regrets that I wouldn't wish upon my worst enemy. I'm working now to go back and do the things I wanted to do, even though my parents discouraged them. Should you listen to your parents when they say don't get a face tattoo? Sure. Should you listen when they try to discourage you from another academic passion? Absolutely not.
If you're miserable at your school, transfer. I can also say this from experience. I transferred twice before I found a school i loved. Picking a school solely based on academics or aid is not always enough. For some people it is, but for others it isn't. My first two schools were in cities I found boring. I like being in an urban environment, and going to a top ranked school not in a metropolitan area was not a good fit. I walked out of both of those schools with stellar grades and disapproving parents, but I traded that in for being comfortable and happy, and I have zero regrets about that.
Look into other options. I would not, under any circumstances, do a diploma program. An ADN maybe, but not a diploma. And honestly, since you're young with good grades, I have no idea why you'd do an ADN either. Just transfer to another four year school. How about a public one where tuition is cheap, you're likely to get scholarships, and you can take out loans for housing expenses? It'll give you an opportunity to get some breathing room from your parents, too, and see what it is that you truly want.
