It gets better. I promise, it does. I am fresh off of my orientation (going into my third week on my own), and I still feel overwhelmed and stressed, but it gets better with every shift that I work. I think you should immediately contact whoever is standing in for your manager, and voice your concerns to her. It's not doing you any good to be with the original preceptor if it causes you this much stress and upset. I do have to be honest though, and tell you that I think "shadowing" for longer than a day is a little excessive. I was hired on for night shift at my facility and during my orientation I did 2 weeks on the day shift and 4 weeks on nights with a preceptor. The very first day I was on they floor (with my day shift preceptor) I shadowed, and it was a great way to familiarize myself with the unit and their procedures. The second day I took two patients of my own, with the understanding that my preceptor was available to answer any questions that I might have or to assist me with anything I might not had experience with. There was also a broadcast over our unit phone system (we use Voceras), that there was a new orientee and if anything interesting or out of the ordinary were to arise to contact myself or my preceptor so that I could be a part of it (I did about a million IV starts, inserted foleys and NGs, etc.), in order to gain familiarity with these procedures while I had somebody with me. The second week I moved up to taking three patients, the third week I took four, and so on. . . By the fifth week, I was managing an assignment of six patients with minimal help from my preceptor, and the last week was really just getting more comfortable with my own routine and figuring out what worked best for me. Just hang in there, and good luck!
