There are two common causes of sidebars falling to the bottom of blogs. They are copying and pasting text and/or importing text. If you have been copying and pasting text from elsewhere without using either icon 5 or icon 6 in Row 2 of the visual editor, then please see here so you know how to do this correctly in the future. http://en.support.wordpress.com/visual-editor/#pasting-text
The reason your sidebar has fallen and is displaying below your posts is either due to copying and pasting or It can also be a result of importing text containing invalid HTML. Typically this is caused by an open HTML tag in one of your posts.
Go to Settings > Writing and select “ ___ WordPress should correct invalidly nested XHTML automatically” and then scroll down and click “Save Changes.”
Now, starting with your latest post, open it in the editor, make one minor change such as adding a space and then deleting it, and then click “Update Post.” Check your blog and see if it is back to normal.
If it’s not, then switch to the HTML editor and look for an open HTML tag and close it. Check your blog again and see if it is back to normal. If it’s still “messed up” then open the next post and do the same thing post by post until it goes back to normal.
