WATCH: Four4Four: Inside Robin Williams’ Tragic Death, And Why Everyone Feels His Loss – people reflect on the life and death of actor Robin Williams.

Robin Williams had been battling severe depression, according to his rep Mara Buxbaum. Last month, Williams publicly stated he was returning to a 12-step treatment program needed after 18 months of nonstop work. He had sought treatment in 2006 after a relapse that ended 20 years of sobriety.

Williams is survived by his wife and his three children: daughter Zelda, 25; and sons Zachary, 31, and Cody, 22. Zelda took to Twitter late Monday to pay tribute to her father by posting a quote from Antoine De Saint-Exupery’s “The Little Prince”:

“This is a tragic loss, and the family respectfully asks for privacy as they grieve in this difficult time,” a Williams family statement read.

Robin Williams won an Academy Award for his role in “Good Will Hunting,” and starred in other blockbusters, such as “Good Morning, Vietnam” and “Bird Cage.” Williams downplayed the award in an interview with comedian Marc Maron back in 2010.

“People say you’re an Academy Award winner,” he said. “The Academy Award lasted about a week and then one week later, people went, ‘Hey Mork!'” Of course, Williams got his break as the brilliant “Mork and Mindy” star.

Unfortunate details of actor Robin Williams death came to light at a press conference Tuesday afternoon.

Williams hung himself with a belt and was discovered by his personal assistant on Monday, said assistant chief deputy coroner Lt. Keith Boyd.

“Mr. Williams’ personal assistant was able to gain access to Mr. Williams’ bedroom and entered the bedroom to find Mr. Williams clothed in a seated position, unresponsive, with a belt secured around his neck with the other end of the [belt] wedged between the… closet door and the door frame,” he said. “His right shoulder area was touching the door with his body perpendicular to the door and slightly suspended.”
