Britney Spears has penned a letter on her personal Web site addressing her recent trip to rehab! Spears writes, "I was sent to a very humbling place called rehab. I truly hit rock bottom. Till this day I don't think that it was alcohol or depression. I was like a bad kid running around with ADD."

Britney also wrote, "There is your side, my side, and the truth. Somebody has to figure it out. I guess we will never really understand or figure out life completely. That's God's job. I can't wait to meet him...or her. Love, Britney."
