have mercy on me.
This is not meant to be snarky, but you need to "write" the essay, not "right" the essay.
I believe that there are five sections to the First Amendment; write a paragraph about each of them.
Start with an overall paragraph (it can be quite short), then the five points, then have a closing paragraph.
None of the five paragraphs need to be long. Can you make each of them a summary of the right and an explanation of the right?
