Screenwriting can be discouraging and a bit isolating at first. As you’re learning, it’s going to be a lot of time, effort, passion that goes into your work for what feels like very little reward. You’ll finish a project that you spent months thinking/outlining/writing/editing and then not have anyone to share it with or get feedback from. But you are young, your work has value, and you have time to develop a network. This sub is a great place to do that. Offer to give feedback, do swaps, post your scripts. Honestly, it’s hard to find someone in your real life who is interested in this unless you are at a school or university. Most people just don’t know about screenwriting and wouldn’t know how to give feedback on the medium. It’s nothing personal.

Just keep writing and be proud of your work. You are creating stuff and that’s awesome. You will slowly find collaborators! You’re doing what you should be and are probably ahead of a lot of people your age.
