I'm not sure it hurts less, but over time, it hurts *differently*.
A physical example of what I mean:
In 2015 I broke my leg really badly. The first pain was horrific. Extreme. As I healed, the pain was bad still, while my bones knitted themselves together and all my flesh slowly regained movement.
Now there are scars which remind me of that moment and sometimes it still causes me pain, but it also reminds me that I have survived.
It's not all that different with emotional hurt.
