Dont be embarrassed,bipol. I find that talking to myself ((outloud)) calms me down, helps me to think more clearly, helps my memory,including remembering lists of things to do and people's names. When I am alone, which is most of the time, I become my own best friend. It is a love-hate relationship. In talking to myself, I am able to work out some of my toughest inner feelings, such as rewarding myself verbally or scolding. I ask myself questions alot. Sarcasm is my favorite thing to use when I am speaking to myself, because It makes me laugh. I like to think I am somewhat witty. I tell myself jokes and even make them up. Overall My inner conciousness is very strong and has been since I was very young. Being an only child, I have spent much of my time alone and if I didnt have me to talk to I would be completely alone and sad.
So I recommend it.. Talk Away! Out loud! In your house, in front of your daughter(Im sure she thinks you are unique anyway), Talk in the car or on the street. Most everyone now has some sort of remote listining device stuck in their ear anyway, so everyone is doing it. If all else fails and you are still embarrassed, just put your finger to one ear and pretend you are with the secret service.

You be you and do what makes you feel comfortable.
Out to Lunch....
