I think that this one:

means exactly what it says: the poster is tired of, not apprehensive about, it.

For what it's worth, I have seen this as a genuine confusion, not typo, of non-native English speakers. (Think, for example, of 'compose' versus 'comprise', and even of 'who' versus 'whom', which neither sound nor look alike, but which are frequently confused even by native speakers.)
