It has been two years since Kyle Robertson woke up out of a three-day coma which left him partially paralysed and unable to speak.

The 22-year-old still has no recollection of what happened in the hours before he received a brutal blow to the head.

Emergency services rushed to save him after his panic-stricken attacker saw him bleeding on the ground and contacted them for help.

Kyle, who has also been left with memory loss as a result of the incident, is now speaking out to warn others about just how dangerous a single punch can be.

His plea comes just days after Michael Christie, the father of an 18-year-old Sydney lad allegedly killed by a single punch, called for tougher laws on alchol-related violence.

In light of a number of ‘one-punch’ incidents recently highlighted in the media, victim Kyle said the attack which happened in Union Street, Largs on November 4, 2012, almost “ruined his life.” He now hopes to warn others of how much of a devastating impact one blow can be.

“I forgive my attacker now,” Kyle said. “It’s amazing to think two years have passed since that night and it’s definitely changed my life.

“One of the thing that bothers me is that I still don’t know what happened that night or why it happened, but I do know that the person who punched me also saved my life by phoning an ambulance.

“There’s no point in being angry or blaming anyone, I just feel blessed that I’m still alive. It’s scary that one punch has left me to deal with epilepsy for the rest of my life.

“One thing I would say is think of the repercussions before you act.” Kyle suffered blood clots, damage to his head and ear and was put on emergency life support, simply because of a single blow to the head.

But, after three days, Kyle battled back and emerged from his coma. He spent the next month in hospital receiving physiotherapy and speech therapy, Kyle was eventually allowed home just in time for Christmas.

But it was then he learned he had also developed epilepsy and memory loss as a result of the attack, something which he still struggles to come to terms with today.

“It’s terrifying when you take a fit,” Kyle admits. “I had no idea how scary epilepsy could be so it’s been difficult being told I’ll have to live with this for the rest of my life.

“The amount of medication I have to take everyday is ridiculous, I get nightmares and flashbacks and sometimes I’m too scared to go out.

“I also have a huge scar across my head, which you can mostly see after I’ve had my hair cut.

“The attack almost ruined my life, but the whole thing has also made me realise you should never take life for granted.” A 28-year-old appeared in court shortly after Kyle’s attack, but the case was found not-proven.

Kyle continued: “Life’s too short to dwell on things, I want to forget about it so I can be at peace now.”
