Thanks again for your email. I disagree. Fiercely. Yes, you are not the only one having the experience you write about, so I agree that you are not unique, in this sense.
However, most people don’t have the competence or the talent to write about that experience the way you do. Their feelings and their understanding of what happened are blurry and confuse. Your words can help them to see their lives and the world clearer. You are unique, in the way that you are one of very few people who are able to formulate this.
You matter, your writing matters,
