Teeth grinding is not that uncommon so don't feel as if you are the only one out there experiencing this. It sounds to me that stress may be a factor is what you are experiencing because stress can manifest in many ways that one can never imagine. I am a witness to that.

I never really realized how stress played such a big part in affecting your body in physical ways. I hope things work out for you, but I belief when you are ready to see someone you will.
