I know teeth grinding is a sign of anxiety, but has anyone ever chewed their tongue unconsciously, or awoken at night because they bit their tongue so hard??

I think this is happening to me.

I wake up periodically from really biting my tongue hard. And today I have remittant tongue pain.

Could I be chewing my tongue instead of grinding my teeth?

Before I begin a major symptom search on the internet which will scare me half to death, anyone have any thoughts on this?
