I had some similar experiences/feelings in nursing school. School hired an adjunct instructor from hell for clinical that I wound up having for 2 clinicals. The absolute worst. Grown women (nursing students) crying, her threatening to fail all of us, she did try to fail me for a minor infraction. Nursing director told her that wasn't gonna happen.
I'm a type A over achiever and I was beat down but it came to pass. My best advice, don't take it personal, keep your head down and nose clean, fly under the radar and don't stand out for the wrong reasons. Stop being late and skipping lectures. Don't give them a reason to fail you. Study like crazy because it's for your own good. Get the good grades that you're capable of. Don't try to psycoanalize the nursing school experience, just go thru it as a means to an end. Before you know it, it will be a memory.
