Ok without knowing the type of internship, some general advise to a newbie...be open to constructive advise of your preceptors, just because someone is telling you that you have done something incorrect doesn't mean they are a bully, or eating young ect...just because school is over that doesn't mean you get to stop studying, you will make mistakes, learn from them!, at first you will be slow, and feel like you don't know what the heck you are doing, don't worry you are and you don't! But every one of us has had those exact feelings, it will come in time. do the work. be proactive, and helpful, even if its not your pt, help. answer a light, ect. well good luck, these are just a few ideas. you'll be fine.
