Acute attacks are moments of great challenge. I described one of mine as being an 11 out of 10 in intensity. Dr. Sarno once said to "grab a bottle of wine and a good book and go to bed." His point being that they tend to run their own course, so hunker down until your brain stops throwing its fit.
In the meantime, during an acute attack the first thing you need to do is gain control over your breathing mechanism. It begins there with deep belly breathing. Then throw in a relaxation ritual. I recommend Dr. Miller's Abolish Anxiety Now but there are many other good ones. The idea is to soothe yourself. Soothe your ANS with breathing, relaxation, and pleasure. You want to add soothing to the rage to begin to balance.
I found doing any type of "responsibility" like journaling made me worse. But others have liked it. In my opinion, there's nothing better than peace and quiet, and compassionate talking. Pour your heart out to someone, it will release the energy from the build-up.
1) Breathe
2) Relax
3) Soothe/pleasure
4) Talk
5) Slow mental chatter
Then, begin the work when it passes.
The work is simple and complex, it's simplex. Also, the idea is not to ignore the pain but to head toward it. The problem lies in your shadow where your deepest pain is stored. Get into it and start to see what it's telling you. The ignoring part comes when you begin the physical movement again. When you do that you act as though pain doesn't exist. But right now, go find out why you need your pain now. It's always a relationship issue, but which one?
Close your eyes and ask yourself why you need your pain right now? Why is your brain trying to help you at this moment? Something has changed recently, what?
Be courageous, this will pass.
