| Which is kind of terrifying to think about - that I could have ceased to exist prior to leaving the womb.|

Is it really that terrifying to think about? If you had never existed you wouldn't know it was terrifying. In fact, it wouldn't affect you at all.

I mean, you could have died in probably several thousand other ways before or since you've been born. Yes, I guess you came close on the abortion one, but there are probably other instances where you don't even know how close you've come to being gravely injured or dying. (Car accidents are a big one that I consider in that regard. Five seconds one way or another in your path and you could have never gotten into an accident...or you could be dead. You don't really know.)

I think it's more terrifying because you know about it than for what it actually is. We don't usually know how close we come to death on a regular basis.

Of course, I'm not trying to tell you how to feel about it. I just don't know if I would find that a terrifying thought, personally. You would never have even known you were going to exist. (Well, probably, I don't know what term your mother was considering aborting.) Hell - you might not even have been you yet in which case ... in which case you wouldn't have died before leaving the womb at all... (?)
