When I hit a block regardless of what I am writing what the subject matter is or what's going on in the plot I go back and I read Pablo Neruda's poetry. I don't actually speak Spanish so I read it translation. But I always go back to Neruda. I don't know why but it calms me calms my brain.
No matter how close to personal experience a story might be inevitably you are going to get to a part that isn't yours and actually whether it happened or not becomes irrelevant. It is all about choosing the right words.
