Wow, that's really awesome!! And it's great that you've already finished and are in the editing stages, even if it does mean a lot of rewriting! Just remember to breathe, and you'll surely get it done! Do you have someone you trust who can beta-read (or the script equivalent to that...)? I find it always helps with I'm re-writing something to have someone read through and tell me if it flows, or if I can do something super simple like moving a paragraph somewhere else to make it all work.

Writing is super hard T_T

ETA: GOOD LUCK with the Wednesday deadline! You can do it‼ \o/
