If you are at your wits end, get a prescription for Lorazepam from your doctor for anxiety. Take one a half hour to a hour before the tournament starts. Make sure you do not take this more often as necessary as it can be addictive. I would think after about 4-5 times your mind should start to naturally retrain its self to not go into anxiety mode. The tournament is a trigger, you just need your mind to break the barrier and the Lorazepam will kick start you on your way. Good luck, let me know when it works.
