The problem takes hold when you start to think instead of feel. What was once instinctive now feels laboured. Doubt grips you like an anaconda, slowly crushing your confidence. One missed chance quickly turns into seven games without a goal. You can't switch off the noise. Boos reverberate around the stadium every time you touch the ball.
Your teammates offer some token words of support, but you know they're simmering with frustration. Your social media mentions hiss with vitriol. You don't want to sulk at home, but it's worse out in public. Nothing offers refuge from the unrelenting loop of frustration and self-loathing.
