It has always been in my nature to help others when they are in need. This is especially true since I am learning to become a nurse. However, I have encountered a tough situation in my nursing classes. I have some classmates who I have studied with in the past and they have become very dependent studying with me. During our past study group sessions, I have lead them all and in essence tutored them to understand the material in the class. They dont' study much on their own and always cram right before a quiz or exam. At this point in the program, I am feeling the need to just study on my own because the material is getting more detailed and intense. I need more time to study and digest it. How can I communicate to my 2 classmates that I can't do group study sessions with them anymore without coming off mean or rude? Am I being selfish? Thanks in advance!
