H'mmm.
Statistical probability dictates: the you [insert name here] that can exist here has a finite probability of existence in other galaxies, superclusters, etc.; and thus, if the universe is infinite, then the matter of whether other duplicates of you, sitting in the exact same chair, thinking the exact same thoughts, reading the exact same livejournal entry, exist, is not one of whether such duplicates exist, but of how many googleplexes of light-years stand between you and the next instance of such a (statistically improbable) duplicate of yourself .

If you are drugged, drunk, confronting a difficult decision: somewhere, someone, bearing your name and indistinguishable (by any means known to science) from you faces the same problem (given an infinite universe, probability dictates it). Furthermore, given that your existence is physically possible, therefore, in an infinite universe, there are an infinite number of duplicates of you facing the exact same problem. If you screw up: there are versions of you doing better; if not, good going.

Let us consider the matter from a totally different angle:

There were kings, upon a time, who lavished upon a beloved entire castles, estates, buildings of the largest possible expense availible to them. Considering that, consider also what that one might think of you who has spent an infinity of stars and superclusters merely to decorate your night sky.
