There is no reason to feel useless. You will find throughout your nursing career that there are people who have power trips and feel that they can talk down upon others. Keep a positive attitude, do well in class and in clinical, and the rest is everyone else's problem. There were times when I felt belittled too. Students take their lumps in nursing school. As far as jumping into critical care right out of school - it can be done. I did it. Teachers will tell you to do med-surg before critical care. It's up to you. You will have a 6 month orientation with a skilled mentor. As far as time management and organization, you will learn that within the first month or two. Once you graduate school, you will find the real learning begins.
