When I returned home I sought help with my drug addiction with a methadone programme. This New Zealand health-funded programme saved my life and I pay tribute to the nurses, doctors and counsellors who were part of it.
Professional and public health services made a real difference. It enabled me to put aside my personal demons and find peace and love in the loving relationship with my family that endures today.
But what really changed me was a job where I experienced first-hand workmates who lost their lives through workplace accidents and coming face to face with families who were struggling.
A lot of people helped me through that period and I became an active and contributing New Zealander.
It is possible to survive drug addiction and people should not be written off because of it. I know it's a hard road and there's no easy answer or formula, but love, support from and for others,empathy with those worse off than ourselves can make the difference.
