I am not a failure

I am not a failure...I keep telling myself as tears stroll down my face reflecting back on this semester. I am currently in my second semester, and although it should be an "easier" semester learning the basics and building my foundation for the rest of the program, I have reached a dilemma. I am not passing my fundamentals 2 class. I am most likely going to have to retake it. I still have 1 more test and a HESI before I make my final decision. Throughout the semester, I have studied with the same study group I always have been successful with, then switched to other groups who are helpful and still could not achieve the results I was working for. I don't know what my issue is, but these tests are really frustrating me. I get the hands on work in clinical, but the test questions are really not making sense to me, until I talk it through with my professor. I have gone through a lot this semester outside of school, and have been isolated by a lot of friends for unknown reasons (hence switching study groups). I am not looking for sympathy whatsoever, but maybe some advice on how you approached this class and words of encouragement that I can get through this. My cohort is the best group of people I could have been surrounded by, and the thought of being "left behind" really scares me. Although it is what it is, I have to accept it and work even harder.

TIA
