'When my legs went from underneath me and my breath stopped coming, just minutes before we were due to go live on The Voice, I knew this was panic at its worst.

Yet in the midst of the madness, something became clear. If I got through this, the secret I had guarded for years with all my life could not remain secret for much longer ...'

In his book, Niall Breslin speaks openly about living with depression and anxiety, and his crippling journey to finally acknowledging 'Jeffrey' - the name he chose for it - years after he took the decision to conceal his growing mental health issues from the world, at age 15.

Told with raw honesty, it is a story of the demons that lay beneath outward success, and how they impacted on his career in sports and later music, as he coped with a condition that at times seemed hell bent on wrecking everything in its wake.

It is also the story of a road to reconciliation with brokenness - beginning after a massive panic attack before a live TV appearance in 2012 - leading to brighter horizons.
