For me, I don't think it'll be a problem. My set back, or my game changer, however you want to look at it, didn't happen in my actual life. My mom was still attacked, but she lived through it. And her death is what looks to have set me on a dramatically different path than what my actual life turned out to be.
But it's hard not thinking about it, or worrying that it might still happen here. But I'm doing my best to push that aside.
