just deal.

Have you ever lost your heart? But kept enough of your mind alive to at least function? It's the worst. Because you're in a weird uncomfortable sort of between-insanity.

It's like doing your math homework while crying. 

You're still able to do the math (and get the right answers) because a part of you feels it's the right thing to do since it's what you were doing before he phoned. And so you continue to figure out what t10 is if t7=1/2 and t2=4.

And after 15 arduous problems... you realize that your worksheets are blotted with tears. 

But you only realize after.
