It's true that most of us will not feel like we know what we're doing for at least a year. With that being said I had a yearly physical and was telling the doctor about the crazy stress level I was experiencing in my job. He said something so simply but so freeing. He said "No one is holding a gun to your head and making you work there. Why don't you try some other position?" I switched jobs, and areas of nursing and my stress problem was gone. Your mental health is important, even if it's a slight pay cut to find something you like.
