Conor Cusack is best known for his time as a hurler with Cloyne, even reaching an All-Ireland final when he represented Cork in 2006.
But he only achieved that after years of battling serious depression.
At his lowest point, his blog reveals that he not only contemplated but planned his suicide.
As Conor notes, "it's not easy baring your soul", but his blog does just that - in the hope that it will send a positive message to others going through similar experiences.
Depression is difficult to explain to people. If you have experienced it, there is no need - if you haven't, I don't think there are words adequate to describe its horror.

He documents how he struggled along, losing interest in family, friends and life, suffering panic attacks and trying to "keep up the pretence" that everything was okay, until he was aged 19.
"I finally cracked. I couldn't do it anymore," he writes.
"I curled up in the corner of the building and began to cry..."
Conor describes his experiences as a "living nightmare".
He writes: "I have had a lot of injuries playing hurling - snapped cruciates, broken bones in my hands 11 times, had my lips sliced in half and all my upper teeth blown out with a dirty pull - but none of them come anywhere near the physical pain and mental torture of depression.
"It permeates every part of your being, from your head to your toes.
"It is never ending, waves and waves of utter despair and hopelessness and fear and darkness flood throughout your whole body. You crave for peace but even sleep doesn't afford that."
As his teammates paraded through town after winning the Under-21 Championship, Conor was taking 18 tablets a day, watching his weight balloon and being offered electric shock therapy.
He refused, no longer believing he could ever get better. He decided to take his own life.
"I knew there was a game on a Saturday evening and that my father and the lads would be gone to that ... my mother and sister would be gone to Mass ..." he writes.
"For some reason, my mother never went to Mass. I don't know why but she didn't go. It was a decision on her part that saved my life."
And in the week that followed, Conor found a psychologist who helped him turn his life around.
"After meeting Tony, I instantly knew this was what I had been searching for. It was the complete opposite of what I felt when I was being prescribed tablets and electric shock therapy ..." he recalls.
"He looked at me with his warm eyes and said: 'I hear you haven't been too well. How are you feeling?' It wasn't even the question - it was the way he asked it.
"I looked at him for about a minute or so and I began to cry. When the tears stopped, I talked and he listened intently."
For Conor, there was a light in the darkness, a renewed interest in a life and a reignited passion for hurling which brought him his successes with Cloyne and Cork.
He also served his time as an electrician and went to college by night, getting a good job. He finished therapy in 2004, and hasn't had a panic attack since or missed a day of work because of depression.
"I came to realise that depression was not my enemy, but my friend," he writes.
"I don't say this lightly. I know the damage it does to people and the lives it has wrecked and is wrecking, so I am only talking for myself ...
"I believe depression is a message from a part of your being to tell you something in your life isn't right and you need to look at it. It forced me to stop and seek within for answers and that is where they are."
Occasionally, that "friend" will still visit - but Conor can deal with that.
Paulo Coelho says in one of his books that ‘A man is at his strongest when he is willing to be vulnerable’. Sadly, society conditions men to be the opposite and views vulnerability as a weakness.
Now he just hopes sharing his blog will help others to see that they too can make it to the other side.
Thousands of people have retweeted a link to his blog, with many of them thanking him for speaking out about depression.
Conor has since appeared on RTÉ to discuss the reaction.
To those who can identify with his experiences, his blog has one overwhelming message.
"There is no situation that is without hope; there is no person that can't overcome their present difficulties. For those that are suffering silently, there is help out there and you are definitely not alone," he says.

"It is an act of courage and strength, not weakness, to admit you are struggling. It is an act of courage to seek help. It is an act of courage to face up to your problems. The most important thing is to take the first step. Please take it."
