"If he needs to talk, he can wait," Uhura said, leaning back and looking up at him with a soft concern in her eyes. "I know you're his best friend, Leonard. And I know you're the ship's physician, and I also know that you're shoved into acting as a pseudo-bartender/therapist half the time. But you can't always go running off when he needs help and forget to worry about yourself," She said. "You need attention to. Everything does not always have to be about James T. Kirk."
And like hell she was going to let him run off in these sorts just to play Agony Aunt to Kirk. Especially not when Kirk didn't even realize what sort of a fuck up he was being. Sure, maybe that was just how he was, but when it was something that made a man that he supposedly cared for feel this bad, he shouldn't have to fucking do it.
"You have to take care of yourself, Leonard. You can't go around fixing everyone else's problems indefinitely without fixing your own first."
