Try not to confuse pain with suffering. Pain is not optional, it is a function of the body. Suffering is the confusion of the mind.
Pain has its limits. The body will die sooner or later and pain will end, as in the case of being mauled by a bear. Suffering knows no limit because it is self-created and self-sustained, as in the cases of resentment, fear, and longing.
When you know that there is no legitimate reason to suffer, and yet feel suffering anyway, then you can use that suffering as a wakeup call to see where you have been buying into useless perspectives and beliefs. But so long as you suffer, and feel that it is justified, you will have a long ride ahead of you.
There is always someone better off than us and always someone worse off, but no one else can fully understand the way we torture ourselves regardless of outward appearances and circumstances. It is up to us to either identify with that suffering and therefore legitimize it, or to criticize that suffering until it yields to clarity.
Between the two, there is no third way. Let go or be dragged.
