Sounds exactly like a thought-stopper to me.
I believe in retrospect that I spent a long while trying to avoid all thought of reality, with a good bit of success, in order to avoid facing my mortality. My vaguely Christian beliefs during that time seem of a piece with this.
Fair enough. Not just that thought-stopper, then. (insofar as they can be distinguished, though I might, as per your example, be completely wrong.)

This post is part of a series rerunning Eliezer Yudkowsky's old posts so those interested can (re-)read and discuss them. The previous post was The Third Alternative, and you can use the sequence_reruns tag or rss feed to follow the rest of the series.
Sequence reruns are a community-driven effort. You can participate by re-reading the sequence post, discussing it, posting the next day's sequence reruns post, summarizing forthcoming articles on the wiki, or creating exercises. Go here for more details, or to discuss the Sequence Reruns.
