I think the biggest think for fury is the lack of recognition. After he beat klitchko I think he was expecting to become a media darling over here in britain. And when that didn't happen he took it very personally. And he thinks it's because he's a gypsy. (Probably true). I can relate in a way to how horrible this is, I come from a broken home and had a terrible start in life yet I'm now a healthcare professional and am the only one in my family to go to university, but my achievements have been unrecognised , it hurts and I think it has hurt him so bad to the point where he just couldn't take it anymore and took to drugs and alcohol. It must sting to see Joshua winning one title from an even older klitchko and have the British media make out it's the second coming of Muhammad Ali.
What are you talking about you dipshit? His issues are caused by himself, not by the people.
He had shown signs of fragility and suicidal thoughts way before the Klitschko fight.
He never looked to be a media darling either: http://www.mirror.co.uk/sport/boxing/tyson-fury-launches-foul-mouthed-7961614
