I find rejection — and even negative review comments associated with major revisions — very difficult. I have put months or years of my best work into a project, spent days or weeks writing it up, submitted it to a journal, pinned hopes on it, and waited for months for a response. And then they say it is not good enough! I can totally understand why you are feeling so unhappy. The aim of the seminar is to discuss the way to deal with a journal rejection and how to write a professional rebuttal letter.
