I, too, am in the exact same boat. Constantly asking myself every day if I can do this, if I'm smart enough, and worst of all if I even LIKE this. I worked so hard to get into the ICU as a new grad and now, 2 months into orientation, I'm ashamed that it might not be for me. Even considering transferring to a tele unit. I hope cath lab works out for you! Best of luck, but know you are not alone.
