My maternal grandfather was one of 6 boys and he, along with a few of his brothers fought in WW1. A couple of his brothers suffered from mustard gas and they all endured awful atrocities, including I have no doubt PTSD, but never a word was spoken.
My father fought for 6 years during WWII in North Africa and Italy. Again never was a word spoken, except to say he hated brussel sprouts (troops had to eat too many during the war) and he'd never take a cruise ship between North America and Europe/UK (bad memories of the troop ship crossings in the North Atlantic).
I think Harry is a very troubled man, but that doesn't excuse his pitiful behaviour. Time to grow up, be accountable for his own actions, begin living in the real world, stop blaming others for his problems, accept the consequences for his own actions and be grateful for the very privileged life he's been given. Before Harry keeps throwing stones at his own family, lets see how his kids turn out - parenting isn't an easy job.
I thought Harry got a C in Art - definitely not a mental giant and he wouldn't have gotten into Sandhurst (not leadership material) without his Royal connection.
