To write or not to write?

I’m being tortured by a story. It’s the 3000-word story that I have to write for uni. I have exactly 12 days left until the deadline. I know exactly what I want this story to be like. But it just won’t write itself… I’m expecting to jump out of bed one night and just type 3000 words without even thinking about it.

The truth is, I’m scared to write longer short fiction. I’m generally scared to write long fiction. This is why my life turned 180° when I discovered short stories - I realised I can write and my text doesn’t have to be dozens of pages long. But there’s a saying - you can’t get rid of the things that scare you. Next year I want to do novel writing and now I want to write a 3000-word short story.

If someone told me they’re scared, I’d say do some writing exercises. Try writing whatever is on your mind and don’t stop until your brain is unstuck. It’s time for me to listen to my own advice. Can I do this? CAN I DO THIS?
