Yes, actually receiving a Stars Gun and falling to the ground shaking and unable to compose himself only caused him emotional damage.
Being squeezed like an orange by Gear 5 while spitting blood and breathing heavily is another mental injury.
And finally being turned into a pizza and crashing into a ship (which saved his life), while he's there breathing heavily and HUFF HUFF is concrete proof that all he suffered was psychological damage.

You can spin as much as you want, and the kizaru was massacred by Yonkou Luffy holding back the entire arc.
