The Talmud states that all suffering is purposeful. When we suffer, we should view it as a message to check our behavior for areas we can improve.

Viewing suffering as meaningless increases one's pain. When you find meaning and purpose in suffering, it becomes much easier to bear. The more meaning you see, the lighter the burden. The worst suffering is when one feels there is no purpose in it.

The basic Torah perspective is that whatever happens to a person is purposeful and ultimately for his good.
