With me at all times almost are atomic fireballs that grounds me fast! A worry stone and just repeating back to myself that I am safe and I know how to kick so if I am in a situation then I will do what I have to, to be safe.
I hope these ideas work out of you, let us all know if they worked or not and ask again there are hundreds of ways to ground yourself Positively!
Great question btw, Peace, and
