I cannot create a summary of the requested article because the article titled "Opinion: I had a brother with schizophrenia. I can't stop thinking about Nick Reiner's siblings" is not found among the search results provided. The available results contain information about the Nick Reiner case and schizophrenia as a disease, but not the article itself that you requested to be summarized. In order to create an accurate and factual summary in accordance with your requirements, I would need access to the full text of this particular article.
