@TheChipmonk If you aren't reading something right now, maybe try to get something. When you read, you may find a phrase, or event that will "jog your memory," so the words will come easier.
@TheChipmonk You may want to try to walk away from writing for a day or two. Your brain continually works on things, whether they are what's on your mind or not, so when you come back, you may have ideas for how to continue. This typically works for me on anything from a math problem to writer's block.
