Yea! I relate to the "living in my head, swirling around with my thoughts, to the point that I am unaware of my surroundings" notion. I live that way, too. I have sprained my ankles each about five times throughout the years, and I believe it was because I was so deep in thought as I was walking that I had no body awareness...

I hope the grounding works for you! I am going to try to practice it today, if I could just get off the computer (OCD!). Have a great day!
