What has Harry endured?

[wizard nelson]

-in GP he gets the guilt of knowing he likely killed innocent mortals with his pyrofeugo spell.
-finding out both his parents died unnatural deaths in FM
-mab freezing his eyeballs(cant think what book)
 -murdered aurora, the final scene with the "neither do i" is chalk full of emotional trauma. SK
-almost tastes death at bobs hands in DB.
and i'll let you know iir any more.

[Romulan Cmdr]

This may be a late addition but - there are plenty of things he endured in Cold Days.

An earlier one was riding in the back of a pickup truck, soaking wet in a full blizzard.
He has a lot of guilt for both unattended consequences of his actions and his not being there.
Like his guilt that Formers invaded.
The macro reactions to his face off in Changes - etc.
The loss of his personal items and home. The place mightve been small but it was his. For someone who d been an orphan to have something that was definitely his meant alot to him.

[Genghiskhan]

Could one potentially be in Storm Front, where he channels the storm without any sort of foci or rituals, to defeat Sells' demon? I'm guessing that would have been something to endure!
