BLOGGER TIP (for blogger blogs): If you push CNTR Z to delete things one time, it will delete what you last did. Do that again, and it deletes your whole post. I've had that happen many times. If you are working on a new post, it's pretty much a lost cause at that point, but if you are editing a post you've published there is still hope. DO NOT SAVE, DO NOT CLOSE OUT. Open your website in another browser window or tab. Find the post and click on the little pencil to edit it. Now, you can close down the tab/window where your deleted post was. Then just click update on the post you have open with the all your text/contect. And it's saved.
