Thank you for the mention :)
Your answer is here — you found it yourself. Your wall is fear. Try writing poetry about the things that are too terrifying to face…even if they just sit in your journal, poetry can be a way to nail down the images, expanding on them into more complex thoughts, and that may lead you around the corner to what you need to write.
I think forcing yourself to write what you plan to write is limiting. Just listen and let the writing take YOU where it wants you to go. I think writing is not the problem for you — submission to the process is.
I loved reading about your writing journey.
