The detective was looking at him "Ah." he takes the glass and drinks some water. Sherlock was hoping that the water would help ease his headache as well. Sherlock wasn't too interested in food. Well he never really was.

"Ah fine." He replied in reponse to having something to eat. Sherlock takes his food and begins eating. He knows John always forces him and would be furious if Lestrade didnt make sure he ate something.
"Know John will be furious if I don't ." He was unsure if Lestrade would call John if he didn't eat.
He was feeling weak and food would help him feel better really.

Sherlock was looking at him. He finished eating. "A case? Your going to let me at least do something?" He was sure that Lestrade had been going to keep him away from all case realted things. He knew he would find it hard to not want to do the big stuff.
He waited for Lestrade to help him up.

He suddenly seemed to be having a panic attack as he remebered what had happned yesterday. It seemed to have sunk in. He was shaking and lowered his head. He held his knees. He looked truely terriied.
Sherlock really needed somebody to help him recover mentally though he didn't want to admit it.
