Why not have somebody who knows what they're doing post on your behalf?
I'd be happy to take a Markdown file of what you were trying to write, and then post it as a long-form read, then linking to you. I did that one time for a new user, and she was pretty impressed with what I was able to do (just some re-formatting was what I did in Obsidian).
I can discuss this further in DM's, and maybe how I'd want it sent (so both of us can protect the metadata that could leak).
