Posted here a while ago, but I think I'll reiterate...
I haven't experienced sever emotional or physical pain, so I really wouldn't know which is worse. But I've experienced more physical pain than emotional pain.
Like AG, I can deal with (some) physical pain. Have to, in karate.
I've been punched and kicked and hurt a lot. Even had my foot broken, but I didn't know it was broken then, so I kept going. (Though that was probably the adrenalin rush... couldn't feel the pain.)
And in the car crash I got into last spring. When everything stopped, I got out, took a few steps, and said "I'm sore all over, but I'll be fine. I've been through worse."
So anyway, I think I can handle physical pain better than I can handle emotional pain. Probably because I've experienced more physical pain.
