Make your home not exist? Destroying it? I'd say that definitely counts as to not having somewhere to go back to. I probably wouldn't really care about getting back so long as I knew AJ and my friends were okay, were here with me.

[She just wants to be sure that AJ will be alright. That Violet and Louis and the rest were okay. If they were here with her, away from the walkers and all, she would see no reason to go back to that otherwise.]
