The Australian actor, who has been in and out of a psychiatric clinic in Sydney since he allegedly attacked then-girlfriend Rachael Taylor last year, said that he has got through a difficult year thanks to rehab and the support of his family.
Newton told a Sydney radio station this morning: "It's been an interesting year for me and a huge one for reflection. I was all over the place... I was a lost soul.
"Going to hospital and having that time to get a sense of who I was, it really allowed me to stop and smell the flowers. It really saved my life. I feel like I'm in the best place I've ever been."
Despite admitting that he had become "estranged from everybody" over the past few months, Newton slammed recent rumours of a rift with his famous parents Bert and Patti Newton, saying: "The only distance between me and my parents is 1,000km - I live in Sydney and they live in Melbourne.
"The great thing about family is they are there through all the ups and downs and they are that core group of people in your life that support you through thick and thin."
Since he appeared in court charged with breaching his AVO from Taylor last year, Newton's lawyer revealed that the star has been diagnosed with bipolar depression, obsessive compulsive disorder and social anxiety.
