Adam Peaty says he's been on a 'self-destructive spiral' but wants to chase more Olympic success

The 28-year-old has been in a class of his own in sprint breaststroke events for nearly a decade but pulled out of the British Championships earlier this month citing mental health issues.

Peaty has spoken previously about periods of depression and problems with alcohol, which he admits worsened last year as he struggled with injury, motivation and the breakdown of his relationship with the mother of his young son.
