everytime i try to improve something, it kind of back fires

i wanted a second sidebar for the left side of my blog so that i could put half the stuff from the one sidebar to another, so it wouldn't be necessary to scroll so far down the page to see everything located in the sidebar. now for some reason my posts don't start until the bottom of the sidebars, making it necessary to scroll even farther down to read any of my posts. if anyone has a solution, please let me know.

UPDATE
i have since switched back to my previous template because i couldn't resolve the issue.
