The former Norwich City striker was handed the punishment earlier today after he pleaded guilty to sending bogus letters to the police in a bid to avoid a driving ban.
The 33-year-old has put his behaviour down to his battle with depression.
"A few years ago, I was not in a good place and couldn't always make sense of what was going on. Some things being personal and some being work related. Unfortunately at that time I fell deep into depression, which led me to try and take my life," read a prepared statement.
"My mindset at the time was confused and not like it is now. Allowing someone to take my points from me, was very stupid of me and I only wish I was in a better place back then and that I could turn back the clock.
"I broke the law six times in that two year period which I am now very aware of . I am truly sorry for these offences that I committed. I must stress to you all, I was not representing the real me back then and realise how stupid I have been.
"Anyone reading this, I hope you take note and learn by my mistakes, especially if you are in a bad place with depression."
McKenzie was sentenced at Northampton Crown Court.
