I do this too, and sometimes I refer to myself in the third person ("Come on, nonnie! You're being silly about this, pull yourself together! Now, do you want to go make cupcakes? Yes. Yes I do. Then let's go make cupcakes.") but I usually only do that when I'm sad and don't have anyone to talk to, or have a really big thing I don't want to do looming. It would probably sound bad to an outsider, but I do know that there is only one of me and it's the same me giving the pep talks and bad advice (well, bad for my teeth, at least) and receiving it.
