Just to give you some advice as a serial procrastinator myself: I started and finished my dissertation (Including surveys, reasearch and analysis) a week before the deadline. Alhamdulillah I got a 2:1 for it.
But I absolutely would not recommend it to anyone. Take this as a warning to NOT fall into the traps that you probabaly have been falling in already.
If you find yourself in this situation: do not panic. Make peace that you've screwed yourself over, and that no matter WHAT happens, you cannot stop writing.
First things first: fill out that reference list. Because you WILL end up forgetting about it and you do NOT want to make a mistake on that. Design the layout for your disso, contents, header, footer, title, acknowledgents, bibliography etc, and then just don't stop writing. Believe me, I had started my disso in the july before it was due, and simply did not complete it until mere minutes before submission.
If you want my advice, complete your literature review now, because honestly, that will eat up a chunk of the word limit, and will form the basis for your whole disso. Even if you come back after some time, you can read through it to fresh up. If I hadn't already had a completed literature review, i really doubt I could have done what I did.
Don't be me! and Good Luck!
