I don't know that time is a "cure." I still miss my Cora every day. It's not the piercing, break-down-into-tears type pain that it was, not every day. But I think it hasn't lessened, I've just gotten used to it. I've learned how to life my life around it. I've gotten more distractions in my life (namely the two named Erin and Patrick). But I still have times when it's just as raw and painful as when the doctor told me Cora's heartbeat was gone.
Anyway, I guess what I'm saying is that you shouldn't feel like there's something "wrong" with you.
