Reddit, I'm stressing out about deadlines in university, does anyone have any advice to deal with it?

It's that time of the year where there are deadlines for essays and studying for exams, and in my own disorganisation I have squandered my time and alas... done very little toward getting my essays done.

I have three essays due in a week, and I am seriously stressed out about them all, and in my stress I put them off so I don't feel it, meaning it gets even worse! It's a never-ending cycle that I'm sure we've all felt before, but how have the people of Reddit dealt with having a big workload that they've put off for so long that it all seems insurmountable?

I've visited /r/GetMotivated but it does nothing to get me going! It all sounds rather self-centred, I know, but I'm hoping that someone else in a similar situation will see this and perhaps get some good advice to help them, too!
