Well writer’s block is common. Sometimes it can be overwhelming but it doesn’t need to be. Give yourself regular breaks whilst writing. If you find it gets quite bad, for example now, take a day or a few days away from writing. Do something else that you enjoy instead. Hopefully, that will give you some motivation or inspiration on what to write. Of course this won’t work for everyone but maybe a small time away from writing without stressing will be good for you regardless.
Have you had anyone review your story and give you feedback? That will give you an insight into what the community wants to see and how they view your story. If you decide to do this, don’t let people’s comments be off-putting - let it be a reason to make your episode better.
Best of luck.
