Nicholas Brendon, the actor best known for his role as Xander Harris on the '90s hit TV show "Buffy the Vampire Slayer," announced that he will be entering rehab for the second time this year, E! News reported. Brendon also hinted at past suicide attempts in a series of Facebook posts published over the weekend.

"I'm going to be going into a 90 day treatment program to fix myself and to understand the traumas of my mind," the 44-year-old actor wrote on Facebook, and thanked his fans for their support. "Life is worth living so let's f--king live it!!"

Brendon has had a rough year, starting with a February arrest after he refused to pay a hotel bill in Florida, as previously reported by HNGN. He was charged with criminal mischief and property damage in March at another Florida hotel, then was arrested in May for public intoxication in South Carolina and entered rehab in June. His most recent arrest was in late September on charges of robbery, obstruction of breathing and criminal mischief after he allegedly choked his girlfriend.

"It's been bad for me the last three years and I've had failed attempts at suicide," Brendon revealed in a second Facebook post. "I really just want to live and love and be filled with Joy. I'm on the long and arduous path to find such things."
