I think the press are largely to blame for her undoing and I include the BBC coverage in this. They all went completely overboard and intruded on her and her families life. She was being hailed as the saviour of England/UK’s female tennis. They did what they usually do and pulled every aspect of her life into the public view. I am not surprised that she crumpled when you add all the hooha to the stress of going so far in the competition, the atmosphere on court, the noise etc. Then there is also the social media pressure and critics who sit and pontificate and pick her life, attitude and ability to bits. No matter how good you are at a sport and think that you can cope with the added pressures, it is not until they actually happen to you, can you find out what it is actually like.
I just hope that she is not put off the sport and manages to recoup and go on. She is only young and I hope she gets good support.
