This is what Hardy had to say about the incident and how it changed him going forward (thank you to Wrestling Inc for the transcription):
"2011, with Sting, I was taking somas and I went out there f--ked up, and, man, I couldn't even wrestle. For the first time in my life, I went too far. I couldn't wrestle my idol, basically, Sting, and he had to do the right thing and shut me down and pin me."
"...that deal with Sting, man, honestly, was the best thing that ever could have happened to me to straighten my ass up."
"That was my eye-opener, for the rest of my life, it was that night with Sting. And, man, I love him so much. He was so great after that and coming back in the best shape of my life in 2012, whenever that was when I won [TNA's] world title again or whatever. Basically, in a way, in a sick way, that was kind of an eye-opener for me to see that and to feel pitiful for myself."
"2012 was one of my best years ever, coming back from that tragedy of a story and just... So basically being on the road so much, I got carried away. The addiction got the best of me."
