It will be okay. I work partime at the news office and was editing and missed the fact that one of the obituaries just ended mid sentence with half of it missing. I felt terrible. I never wanted to do it again. It ended up okay and the fact that I caught a whole bunch of other problems that people missed showed that I wasn't awful at the job. I'm sure you have written previous articles that were really good and prove your worth. I don't know if any of this helps at all but I hope it does. It is all the advice I have. Okay so not much of advice...but I hope it makes you feel better.
