Not in particular...the idea of not being with my family after I die did scare me but the idea didn't hold up since the mormon idea of hell is a special subject. But I did fear a lot on the idea of "being an apostate," losing the spirit, falling away from god, and being in Satan's grasp. Now that is the nonsense that tormented me for a minute. And my deconversation was !.5 years ago and it took until just about a month ago to let go of all that "Satan has got me" rubbish.
