Wanting to transfer to nursing school

This is my first post and so I really hope I am in the right place here and apologize if this is a long post.I am a university student who was lost future-career wise and went to business school, hated it but worked hard but however didn't pursue the next steps. Took last semester off and thought of what interested me as tough as it was 'disappointing my family'. I thought of anatomy and health related fields and yet somewhere where I can help others. Now I am taking online high school chemistry and biology credits that I didn't do in highschool, and a few months ago applied to nursing school. I was hoping someone/anyone could give me advice or some personal experiences in nursing school, what I can expect, how hard is it to cope and get used to the daily responsibilities, how hard it is to pass the new NCLEX for Canadians and anything else! Seriously any information is so appreciated. I just want to be prepared for a decision that I have been seriously considering for the past several months and am working hard towards. Thanks.
