Hello, today I submitted a paper I worked really hard on for my University history paper. However, I submitted the wrong file which has a few references missing. All citations in the essay are perfect which makes me hope it won't be classed as plagiarism. I'm going to email my course leader about the error and send her the correct references. However, I'm so scared that this issue is huge and will get in a lot of trouble. I keep thinking that my life is now over and I've screwed everything up by this mistake. I really need some help calming down. Thank you so much in advance.
