Really Fed Up!

Okay, does anybody have any clue how to get the formatting on this blog to go back to normal? All other posts, except the last two, have published just as I typed them. However, on the last two, they've cdombined my multiple paragraphs into one big mass of words. It not only is hard to read, but it looks stupid. I really would like to get the thing back to normal, but I can't figure it out. Any help would be appreciated.
