Ker,
So sorry you deal with this crap! I have soooo much anxiety and it ebbs and flows ya know.

Yes, grounding techniques, touch, hugs, touching or tapping the floor etc../touching things help me. Overall, I have to pop a xanax or a valium tho. Try some deep breathing and slowing stuff down. Taking pressure off yourself can help if you can.

Watch that caffeine when you feel this way. If you don't have an alcohol problem, then a stiff shot will help ya ease up or a nice slow glass of wine......

Sometimes a good yell or scream (but that can also agrravate) And finally, EXCERCISE or stretch those muscles to get some oxygen flowing in all the "parts"....
