Claustrophobia

I wrestled for 10 years and I have been doing jiu jitsu for 10 years. Now I’m a 40 year old purple belt and I develop claustrophobia out of no where. Now I panic when I’m on my back and I’m not sure how to fix it. When I roll, I turtle when I’m mounted because I don’t panic there. But I can’t fix my head. Has this happened to anyone and is there a solution.
