"If you have an OCD compulsion, the more you do it, the more your brain wants to keep doing it to make yourself feel better. So when you're by yourself like that and you have every opportunity to do it, it gets stronger and stronger and stronger. I would go to the rink and we would be on the ice for an hour and a half and I couldn't do those things for an hour and a half, I couldn't do it anymore. I'd be shaking."
