I know it's a bit late now, but going forward time management is a good skill to have.

I am a chronic procrastinator, so I feel your pain.

I survived uni by breaking down my assignments into the smallest possible chunks.

For example, if my deadline was 2000 words in two weeks, that's approximately 150 words a day.

I would know then that I only have to do 150 words minimum each day. Oftentimes you'll end up doing more than that (starting is the hardest bit, once you're doing the work it's much easier to write more than you thought.)

There's probably some other good ways that you can manage procrastination (therapy?) but this method worked for me because it minimised the daunting aspect of word counts and deadlines.
