How to lower the stress level

Does anyone have any advice for decreasing the stress level and worry that comes with being a new nurse? There is such a huge learning curve and it causes a great amount of stress and worry for me. Any ideas????
I think that being organized helps a lot, ask a lot of questions and being in a supportive work environment. These all help to decrease the stress level of a new nurse and always remain teachable. How long have you been a nurse and what type of facility do you work in, hospital or SNF?
