Congrats on graduation and landing a job. Earning your RN doesn't mean you know everything you are supposed to know to take care of your patients. Its a start, a base of knowledge. Companies are aware of that and that is why they do offer such long orientations and preceptors. It sounds like they notice you are struggling and are trying to help you. How is your preceptor? Do you take half the patients as your own and build up to the full load? i would make sure your manager is aware of your concerns and can give you feedback.
