First year nursing school

Hiya. I feel so relieved that I at least have a school to go to. I graduated with a bachelor's in biochemistry with 3.3 undergrad GPA and a 1380 GRE score. I applied to 6 master's entry schools.

I am currently in my third week of my first semester at nursing school. There is so much to learn and not enough time to learn it. All these bugs and drugs are hurting my head. To think, I still have four more years of this.
What is really annoying are the questions I get from people like, So...when are you going to become a doctor? Or the ever annoying, why is it going to take another 4 years?
How did you all deal with nursing school?
