Nurse Malpractice Insurance

I just graduated with my BSN. I've always wanted a family nurse practitioner (8 years), but recently the idea of a practitioner took my interest. I searched the internet for some pros and cons, but I can not decide which direction I go. I love the interaction I have with my patients and I do not want to lose that money is not an issue. I love what I do, and that to me is more important than any dollar amount (although somehow, I would rather live as comfortably). I guess I would be employment. If I understand correctly, I can go to medical school with my BSN degree and not in advance. Is it true? So what's the difference between professional responsibility? If I worked at a hospital, they must pay for it (I'm sure it depends, but generally?) Do you have any suggestions or ideas would be appreciated. Thanks!
