I can understand your anxiety. However, I have only been a nurse for a short time (maybe 2months). I cannot sleep, every time my phone rings I panic thinking its my job, and I've done something awful! I wake up all through out the night thinking I've forgotten something at work and fear I'll get into trouble. I'm hoping all this anxiety is. Because I'm new and will decrease with time. I love this profession but my fear of really messing up and hurting someone is taking its toll on me. Any advice you get, please pass to me as well! Good luck!
