Drop out.

Is it wrong that I don't have the motive to go to my classes ? No one supports me or ask me about school. My parents always check up on my brother but never I and every day I just feel less motivated to continue taking my courses. I'm going for nursing but each day I just wanna drop out even more. Is this just a phase that will pass ? I mean I really wanna be a nurse but I'm also scared of failure from joking the nursing program. I'm taking a course that gets me into the program if I pass the exam but I'm thinking about dropping out instead. How can I stop feeling like this ??
