After a year of questionable behavior, Jon Gosselin turned to his Twitter account Tuesday to clear his conscience and get some things off his chest.

"I am acutely aware of the mistakes I made in 2009 and I am ashamed of the choices I made," Jon wrote, according to "I have apologized to Kate, my family, and to my friends. Through counseling I have learned to own my actions. My goal is to move forward in a positive direction."

Gosselin said his reason for Tuesday's Twitter diatribe was to "clarify a few things" and share how being on TV has impacted his kids negatively. "The negative effects on my family was my greatest concern and far outweigh any monetary gain we received," Gosselin Tweeted.
