Physical pain is by far the worst of the two. Emotional pain is all in your head, there are several methods to easily and healthily deal with such (depending on your personality and whatnot). It's honestly easy to deal with, especially if you have any degree of discipline.
Physical pain on the other hand is much harder to deal with without narcotics. It's nigh impossible to ignore, by virtue of the fact that it's specifically designed that way, and it can be all consuming all too easily.
Emotional pain can be dealt with and processed over long periods. Physical does not have that luxury. It is right now, and always will be until you heal.
