Aww, so sad, you can tell how much pain John is in. The way his eyes are puffy like he hasn't stopped crying, and the way he's literally shaking because he's sobbing so hard. I can't even imagine what Watson went through when he lost Sherlock. There relationship was so special, they were more than friends, lovers or brothers, to loose someone like that has got to be so unbearably painful that it's indescribable. It hurt so much that John was haunted and in pain even three years later.
