My advice is to possibly look for a job elsewhere in another specialty (postpartum possibly)...you earned your one year of med surge experience which looks awesome on your resume. Med surge isn't for everyone so find what fits YOU and makes YOU happy. And when you're at work and you start to feel stressed, go to the med room or somewhere quiet and take a breather, clear your head and gather your thoughts. Never give up on yourself and remember that what doesn't kill you makes you stronger.
Best of luck!!:)
