The good news is you're totally normal. As a new nurse and in a new job, feeling totally incompetent and overwhelmed is EXACTLY how you should be feeling! It will get better with time, but for now, just get comfortable with being UNCOMFORTABLE. Sounds weird, but I promise you, that is the way to continue to grow and challenge yourself. There's a podcast I recommend called Thriving Nurse that talks all about this. I think you'd really enjoy the episode called New Nurse Thought Traps. Hope it helps and best of luck!
