It occurs to me, I may not have said how to do that.
You have to go to a post and click the edit button then
1. Click on the button (with 3 dots ) on the top right of the post you are editing.
2. Scroll down to the very bottom and you will find an option which says “Switch to Classic Editor”. Click that and you are done.
It carries over to new posts, thank goodness.

I may have mentioned how much I hate the new editor. WTF, WordPress? So I searched for ways to get rid of it. I am not the only one who hates it. Not even. So I’m told to go to plugins and blah, blah, blah and when I go there, in order to do anything with plugins, my page says I have to buy WordPress Business for somewhere between 200 and 300 dollars. None of the articles I read mentioned this minor detail. Dear WordPress. You have a very unhappy user here, after years of being very pleased. I will move my blog if I have to, because I am so over being forced to accept changes that make things worse/harder/more complicated. Some asshat at Google doesn’t like Google Reader, gone. My bank has a go through this account check in five easy steps turn into five minutes of blah, blah, blah instead. Windows. Don’t even get me started on Windows. Windows 10, the curse of the internet. The world is going to hell, and WordPress just wants to create more stress for it’s users. WTF, WordPress? WTF?
Update. Got a bit peeved with WP chat and just left in the middle. My bad. Then I found a fix, but if it’s just for the post you’re editing, not making new posts, it’s not much of one. We’ll see. Frustrated Jean is so freaking frustrated with every single thing there is right now. And I haven’t even made it to Twitter or Tumblr yet today. Sheesh!
