Why move to the US? We need nurses here (in Canada) too! Does it have anything to the "only woman I have ever wanted to marry"? Not trying to imply this is the reason, just noticed a connection.
As for right and wrong reasons to become an RN, those are individual, and there's no one right or wrong answer. Repeating Shandy Lynn's question, "Why exactly do you think nursing is what you want to do?" I think when you give your reasons, you'll be able to look at them and see if they are realistic expectations to have. Is it just a vague feeling, or are there specific reasons for your interest in nursing?
I'm becoming a nurse b/c at the end of high school, I had no idea what I wanted to do, and medicine had always fascinated me. That, and I didn't wanna take science in university! Now that I'm in school, I love it, and I'm pretty sure I'm in the right place.
To me, wrong reasons to become a nurse would be having unrealistic expectations of what nursing will fulfull for you. Things like "I wanna make lots of money", "I wanna have good hours", "I wanna have an easy job"... things that just don't happen! (at least not from what I can tell)
Can a person leave their job at the hospital? I'm not sure yet. So far so good, but I just had clinical placements once a week. I think this is very individual as well. Some people are just better at it than others. Think about this in relation to other things in your life. If you've had a bad or frustrating day, does it keep you up at night? What about your current business- do you carry that home, or leave it at work?
Curious about your "couldn't care less what others think" attitude, when you state your reluctance to tell friends about your interest in nursing. Is it only strangers' opinions who you couldn't care less about? Maybe you're more insecure than you want to admit(?)
I'd suggest talking to some of the nurses you know... ask them about their jobs. Ask people you know if they can see you as a nurse. When I tell people I'm in nursing, they often say, "I can sooo see you as a nurse!"
So, in summary, some questions:
Why exactly do you think nursing is what you want to do?
What are your expectations of nursing? What do you think you will gain by being a nurse? What will nursing fulfill for you that your current job does not?
Why are you hesitant to tell others about your interest in nursing?
How long have you been considering this?
Good luck in making a decision!
