Alice Cooper - I Never Cry Lyrics Meaning

An alcoholic who kills his pain through endless nights of alcohol binges until late into the night where he passes out to waken with the sound of the tv broadcasting white noise.
His binges become so severe that he becomes almost inhuman and feels no pain what so ever Until one day he realizes he has no one but himself.
His way of apologizing for being an asshole is through the words, I wish I were blind." This part symbolizes the destruction he knows he created when he was drunk and he has no wish to see the anguish he causes when he is under the black cloud of alcoholism.The heartache that got caught in his eye.
This song is so awesome I swear as a former alcoholic it has helped me through some difficult times. I have no idea if it was written to be symbolic of the effects of alcoholism but to me it sounds like he is begging for forgiveness for the many nights of being a fricked out drunk.
