I tried streaming for the first time over the weekend. Damn is it hard to keep talking for multiple hours straight. Especially when there's zero messages in the chat. Streamers make it look normal but damn is it not
Get a producer or anyone with you and talk to them. That's how radio and TV broadcasters used to do it. They would talk to the console or camera operator. Eventually it becomes natural to talk by yourself. It does look like unhinged behavior without the context. But it is an old skill, as old as radio broadcast. Try acting monologues to yourself, it also helps.
I have thought about showing off my gigantic single player creative mode Minecraft map through a live stream for years, I spent most of my free time over a decade of manually just building huge, huge structures.
And pretending to show it off to a live stream, talking about it and explaining it makes it easier to remember what/why/how I built stuff...
Anon should just do a stream and do their best and hope one of the popular streamers/youtubers pity them and give them a donation and a shoutout to a massive audience.
