"I know, Doctor. It always feels that way. Like a weight's been put on your shoulders that's impossible to bear.", he frowned, pulling back a bit so he could look the other in the yes, gently wiping away any stray tears. "You can though and you will. Trust me on that. You're a lot stronger than anyone I know. And definitely way stronger than I am now. You've never given up before and you won't now because you don't do that. You're the Doctor. Brilliant and impossible and just stubborn enough to get you through anything. You may not believe in yourself, but I do. More than anything."
