I have a big problem. Basically I'm in my 4th semester out of 5 and I want to quit my nursing program. It's a long story but basically I never even wanted to be a nurse or apply to the program. I only did because my parents and family kept urging me to do so. From the very first day of class I knew that nursing wasn't for me...well actually I felt this way before applying to nursing school. I am very shy/quiet, I have a fear of seeing, hearing, smelling vomit, and I am not a people person. I am severely depressed. I cry every night just about. I have been this way since the beginning of the program. I am so unhappy and I dread everyday of school, especially clinicals. Clinicals is the worst part of the program. I begged and begged my parents early on to let me pursue another major but they said that's not an option for me. I feel so trapped. I was paying for my own education 1st semester but ended up taking out loans 2nd semester onward. I feel mentally sick and pure miserable. I have zero motivation. I was barely getting by anyways...I've failed or barely passed every test we've had thus far. The only reason I passed was all the assignments/projects/quizzes gave me a boost. Guys what should I do? I have even had thoughts of suicide I am just so depressed. I need some help. What would you do?
