Since you've been working on your script for a long period of time, save the file and focus on something else for a few weeks. That way, when you come back to edit it, you'll be able to look at it with fresh eyes. Start work on another script while you wait if you want to keep working on other ideas. Open your script and read it from start to end. Look for places where the story is the confusing or where characters are doing things without moving the story forward. Write your notes down by hand so you can remember them better. Try to read your script out loud and don't be afraid to act out parts based on how you think they should be performed. That way, you can catch dialogue or wording that doesn't work as well. Ask a friend or parent to look over your script to see what they think. Tell them what sort of feedback you're looking for so they know what to focus on. Ask them questions when they're finished about whether parts make sense or not. Work on story and character revisions first to fix larger problems in your script. As you work through each revision, work from larger problems, such as dialogue or confusing action sequences, to minor problems, such as grammar and spelling.  Start each draft in a new document so you can cut and paste parts you like from your old script into the new one. Don't get too nit-picky with yourself or you'll never finish the script you're working on.
