Working in the ER

Hello everyone. This is my first post, but I am really trying to get some advice on something. I am a nursing student and am doing well in school. I really enjoy my clinicals and love taking care of my patients. I do not even mind giving them bed bath or changing dirty depends. I feel like I provide the best care that I possible can at this level of my nursing school career.
I recently took a job in the ER as a tech at a local hospital. I thought I would gain a lot of experience. I do not like it!!!! This really scares me because I have put so much time and money into school. I feel as if the nurses there think I am an idiot. I am new to medicine and there is a lot I do not know about medicine, but I am not an idiot. Maybe it is my confidence level because it is something new. I feel like in the ER I do not get to build a rapport with the staff or the patients. I am a warm, compassionate person who is all about relationships.
I often ask myself if it is nursing I am hating or if it is the ER. Maybe I am just not cut out to work in the ER or is it that I am too sensitive to be a nurse. I cry at the thought of having to go back into the ER. Please Help!!!!! All advice welcome.

Thanks
