Removing Big White Space Between Top Couple Widgets and Bottom Couple

There is a huge white space between the top couple widgets on my sidebar and the bottom couple? My blog is: http://www.PrayersAndApples.com. At first, I thought it was just a problem with my YouTube Sidebar Widget – it would say the title (“Videos”) and then put a TON of white space between the title and the videos. So i got rid of that widget. And now it’s just divided me widgets in half and put the first couple at the top of page and the last ones at the bottom. It’s as if something is telling it to evenly space out the widgets to take up the whole length of the page (although instead of putting even spacing between each widget, it just fills up the whole middle of the page with white). Any suggestions? (Thanks in advance!)
