If this is your work, OP, PTSD and ADD weren't referred to as such until the modern era. Dead giveaway.

For the time period you're depicting here, PTSD would be "battle fatigue" or "shell shock", and ADD was pretty unknown and would probably just fall under "hyperactivity".

Thank you. Had to scroll through half the comments to make sure someone pointed out this is fake. I never heard the terms PTSD or ADD until *maybe* the late 80s, if that.

Nice try, tho, OP! You might have fooled a few young ‘uns!
