It's not self-obsession to feel like you need to take care of yourself after you've been hurt. And it's not whining to talk about it. Dean and I just put you through hell. I know, because I've been on both ends of it. Everyone has weak spots, and demons are professionals at finding them. Especially demons who happen to be your boyfriend, or your boyfriend's brother.
I'll feel better, too, if there's something I can do or say to reassure you. So don't feel like you have to hold back on my account.
