He started by telling friends and followers on his page last night, "I have a confession to make, for the last few months I have been struggling with depression."
King has often spoken publicly about his tumultuous personal life, including revelations of a cocaine bender in 2009 and mental health issues that saw him attempt to take his own life.
But yesterday, he posted how he had been consumed by depression over the past few months that left him being overwhelmed in a "vicious cycle" of "frustration, and anger, followed by regret, remorse and inevitably back to anger".
"A vicious cycle that kept repeating itself day in day out. And still I didn't think I had a problem, 'surely it was everyone else's fault, after all I'm the one who's getting hurt' was my reasoning."
He wrote how he threw himself into his work and if he wasn't working he was painting, "anything to keep myself busy, anything to stop that annoying voice in my head telling me I was useless."
But he managed to pull himself out of it while working on a TV project in Dunedin with good friend Dale Husband, who he described as one of those "beautiful souls who 'sees the good in everything and everyone and likes nothing more than brightening people's days with a kind word'.
"We were standing in the Octagon getting ready for another full on day of filming when Dale started charming a group of locals and making them laugh. The first thought that popped in my head when I heard them was 'oh for f*** sake will you shut up! No one can be that happy all the time, surely?'
"And that's when the penny dropped. Within a millisecond of that thought popping in my head I said out loud to myself 'you've got a problem and you need to get it sorted!'."
He wrote how at first he thought he was just having a few bad days which would pass, but as the days turned into weeks, and the weeks turned into months things got worse.
"But here's the thing, instead of recognising I had a problem, I thought everybody else was the problem. That's the nature of depression. When you're in it, it overwhelms you. Little by little it takes over, it dominates and then finally it suffocates you. I became highly sensitive and very negative. Other people's looks and comments would be misinterpreted which led to frustration and anger, followed by regret, remorse and inevitably back to anger. To cope I threw myself into my mahi [work], and when I wasn't working I was painting."
He felt as though a weight had been lifted off his shoulders, but was then struck by emotion and guilt "at what a nightmare I must have put my loved ones through while fighting my demons".
He recalled seeing the apprehension in partner Jo Methven's eyes when he walked in the motel door that night and relief when he said he'd make an appointment with the doctor.
"That's when she hugged me and said 'that's a really good idea babe' but I knew in her head she was saying 'thank f*** for that' and rightly so," he wrote.
