" Nic begins writing hard, a word, I, two words, am, three words, sorry, writes them again, writes them again, writes them again, writes them again. He cannot, it seems, stop writing them. It is bullshit, a cheap attempt at - it is not bullshit, he is trying with excruciating desperation, which I can feel coming from him, to say something, to get out something that he cannot get out.
It's easy to forget that no matter how hard it is for us, it is harder for him. "

― David Sheff , Beautiful Boy: A Father's Journey Through His Son's Addiction
