''It's a constant stress and a constant pressure when you're in a farming environment that your stock are suffering or unhappy, your staff are not happy, you're looking at people driving by and wondering what they're thinking or looking at, and we're working long hours and highly strung-out.''
As a boss, certain times of year involved many long days, little to no time off, and many sleepless nights, he said.
''Now in calving season, I have to regularly check on the cows throughout the day and I go out twice in the night to check because they might need help and I don't sleep.''
All of which, plus past trauma from surviving the 2011 Christchurch earthquake, two car crashes, and his wife Sandy finding tumours on her lungs, led to the day he ''snapped'', he said.
''It's hard to talk about and to comprehend I even went that far, but I had no control.''
It was only then did he get the help he did not know was out there, he said.
''I hid from everyone for a long time because I was so ashamed, but the people who came to visit me expressed their own stories, some had lost their children to suicide and I didn't even know.''
Now attending regular therapy sessions and working with his doctor to find the right medication, he was on his way to getting back on his feet, he said.
''I still have bad days, but talking about it is the key for me. If my situation can help one or two other people I'll be happy.''
A member of the newly established group ''Ag Proud NZ'', Herrick wanted to use his experience to raise awareness about the pressures associated with the agricultural industry, and to promote ''positive practices'' within it.
