Complete lack of self-awareness.

From The Metro:

THE father of a Team GB snowboarder who died on her 18th birthday has said missing a flight to a training camp tipped her ‘over the edge’. Tony Soutter said Ellie had battled mental health problems and struggled with the pressure of top-level sport.

He said: "Unfortunately it all came about from missing a flight, which meant she didn’t go training with the GB squad. She felt she had let them down, she felt she had let me down. And tragically it just takes one silly little thing like that to tip somebody over the edge because there’s a lot of pressure on children...

"That was a lot to do with the fact that she wasn’t able to compete last season and do what she would have loved to have done through a total lack of funding. I have lost my best friend. She was my rock. I’ve done nothing but live for her for 18 years. Now I’ve got to start all over again really. If I didn’t she’d be mortified."
