Focus attention on the feeling inside you.
Know that it is the pain-body.
Accept that it is there.
Don't think about it - don't let the feeling turn into thinking.
Don't judge or analyze.
Don't make an identity for yourself out of it.
Stay present, and continue to be the observer of what is happening inside you.
Become aware not only of the emotional pain but also of "the one who observes," the silent watcher.
This is the power of the Now, the power of your own conscious presence.
Then see what happens.
