What to do, though? How to approach writing? As I noted, you don’t want to start at the very end, trying to add some words to a finished project. Start writing while you’re in the middle. Every photographer should write (and read – a lot). The act of committing thoughts to paper – or hacking them into a computer – is more liberating than you’d imagine. You are probably only going to use a small fraction of all the writing, but you will be surprised what your subconsciousness can come up with – the same subconsciousness that’s responsible for so much in your photographs.
