Scripts are a way of planning what will happen. They don't have to look beautiful for anyone. They need to help you plan for your storytelling, and communicate the plan to everyone else. If the actors are going to speak lines you may use a traditional script, but if you are going to improvise, or your storytelling style is visual- maybe you just need an outline, or a storyboard.
The great advantage of making a film version is that it doesn't have to be done perfectly all at once. The story can be cut into bite size pieces. You can even memorize the lines right before shooting to make it easier.
Here's a great guide to breaking down your script into a shot list:

An establishing shot shows us where we are. It can set the scene and the tone of your story. Maybe we open on a shot of the raging ocean, or an image of Cerce brewing a potion. This shot should be 3-5 seconds long. If you're filming at home- use your phone to film an image of the place where the scene is set, or grab a clip from youtube of a location you want to use.
Here's a great tutorial and look at establishing shots:
Wide shots have the camera far enough away to show action. Use these if the characters are moving, fighting, or if you want to show where they are.
A medium shot usually shows your characters from the chest up. It can have one or two characters, and we use it to show dialogue.
A Close-up shot would be used to show a character's emotion. Use them when you want the audience to know how the character feels.
Reaction shots fall in between the lines of dialogue or the action of the scene to show us how another character is feeling about what just happened.
This is the performance moment. Gather everything you need. Plan the placement of the camera. Do your best to light things the way you want to. When you shoot make sure to hold the pose of the scene a few extra seconds before turning to stop your camera- this way you can cut out the moments that show how you made it.
