Has anyone ever felt completely trapped by a deadline?

I usually leave myself enough time for assignments but this time everything went wrong. I was sick for a few days and then had to catch up on classes which pushed all my work back. Now I have an essay due very soon and I am nowhere near finished. Last night I was sitting at my desk feeling stressed and disappointed in myself. I got so desperate that I even started thinking about whether I should buy an essay UK students sometimes talk about when deadlines get out of control. I know that thought came from panic but it shows how overwhelmed I feel right now. Has anyone else been in a situation like this?
