What can you learn from your pain?

Sparked by an answer by thorninmud on another question. I’ve been thinking about it in terms of the unresolved childhood wounds that current losses trigger but physical pain can also be included. I am trying to learn to carry the pain more comfortably than I do at times and to know I can withstand it. And that I am not the helpless child who was so hurt at times by others. What has pain taught you?
