especially when your whole reason for being born was to be a hero he probably grew up being told he would be one and surpass the number one hero until this point

I think what might have helped is if Endeavour had not told Touya he couldn't be a hero. You remember how that crushed Midoriya and his parents (as far as we know) weren't even heroes? For Touya to be the #2's son and not only not be able to surpass All Might, but not even be considered any good as a hero was probably devastating.
Perhaps it was possible for him to still be a hero and use his powers but just not use them at full strength, and perhaps some kind of support item to keep him from hurting himself could have been used.
