Meta cognition / hyperawareness / monitoring of thoughts

Just want to know if there are any buddies that suffer from this horrific symptom. Constantly monitoring everything thought and action you make. It feels like you're not control your brain, like you're a passenger and your brain has a mind of its own. I know one buddies that recovered from this, liveaboveit, I'd like to talk to others who have this symptom and Share experiences and coping skills. This I consider my worst symptom, specially during derealization.
