I'm ending my first semester of Nursing Program and I will tell you, it's ok to be nervous/scared but don't let those nerves throw you out of the game. Some of that anxiety is good because it will keep you focused and ready to learn, just learn to check it and how to pull back n relax when you need to. As far as the instructors being rough. I had one of the roughest and at this point I am so thankful for it. She's not mean at all she is passionate about what she does. She wants to make us the best nurses we can be and sometimes that process looks pretty ugly but being on the other side now I thank her. Hang in there and relax, learn and always always always ask questions if you don't know and trust your gut.
