papillon76, the anxiety can really increase your nighttime clenching/bruxing. Consider a gettting a positioning splint (aka bionator) that prevents your molars from touching. And get a real splint, not an NTI device, because those are okay for daytime, but at night, your lower jaw can slip down or sideways (depending on your sleeping position) off the NTI device. I tried one and it was useless for night-time.
Don't let things get worse and worse, cuz I did that for years, and it took a lot of (expensive) splint therapy to get everything fixed. But it's better than being in pain or ending up needing surgery.
