Hey girl! I'm actually a nursing student who works in healthcare also! No, my boss or others don't know. And you can leave it like that. At the end of the day ur able to get ur message across and that's what matters! I'm sure they know that somethings up and if they haven't bothered talking to you about it then don't worry too much. Just keep going! There's no right or wrong answer in whether you should tell them or not. I'm just more comfortable with moving along with it. If your scared to tell them don't stress about it. You've been doing this, what makes you think you can't keep doing it? Go to work everyday and try ur hardest!
