I'm currently struggling with how to answer the question "Do I want to be a nurse?"

I was super sure I wanted to be a nurse for awhile, and then A&P came along. I struggled with it a lot and barely made it through A&P I but did well in A&P II. I then felt confident again that I wanted to be a nurse. At that point, I actually started nursing school. I loved it at first, and I did well throughout the entire semester, but maybe halfway through I started questioning if nursing was what I really wanted. It didn't help that mental health wise I wasn't doing well at all. I decided to take the spring semester off from nursing, and during that time decided that I wanted to change my major...to what, I wasn't sure. Over the summer I was thinking I'd like to be a teacher...another respectable career which I have some experience in. I took this semester off partly because of mental health and partly because I'm just not sure what I want to do. I'm doing well mental health wise, and am going back to school next semester so I have to decide and answer the big question. How in the world do you do that?
