Blogger Help? Change dates on posts?

Okay -- any bloggers out there? Here's my problem. Clearly, I'm a self-involved maniac. I have soo much stuff I want to put on this blog, I often write a "post" and save it as a "draft". However -- days later, when I push "publish" -- it goes up on the blog, but ends up NOT being the first post on the page. Even when I try to change the "DATE" of the post -- it hangs on to the original date I WROTE the post.

So the new post gets buried...AND, if somebody comes to the blog every day, they would, of course, only read the top post...

Anybody have an answer for this blogging riddle?? Email me at: ritafar@aol.com

THANKS...
