Steve-O’s back in the Looney Bin. Steve was first hospitalized at a mental health unit of L.A.’s Cedars-Sinai Medical Center in March. The stunt enthusiast has once entered a mental institution to battle depression and cocaine dependency.

“I’ve now been clean for 115 days, and I’m, again, in a mental institution,” the thirty-three year old Jackass star wrote on his Myspace blog Sunday. “I did so much cocaine, ketamine, pcp, nitrous oxide, and all sorts of other drugs, that, quite simply, my brain is fuckd up.”

“I frequently suffer from horrible mood swings and severe depression….Medication that is prescribed to me doesn’t do the trick every day. I’m back in the looney bin trying to get that shit right.”

“The bottom line is that doing drugs fuicked my ass up, and I’m going to be paying for it for a long time, probably for the rest of my life,” he says. “Everyone’s going to make their own decisions in life, but nobody needs to make the same mistakes I made.”
