I mean...if I needed someone to yell at me, console me, smack me or lift me up...I do it myself. I am my authority figure, mate and friend...just clearing up what I said before.
No. I mean...I talk to myself probably constantly but never to help me. I've never targeted my own conversations objectively...never thought to do it. You're onto something. I haven't during casual talk but I have once in awhile purposely posed questions to myself to help myself because I had to because there was noone else around to talk to.
I've found a simple technique to combat withdrawal has been to talk to myself out loud while alone. I engage myself in conversation as I mull something over. I've worked out a few personal problems like this with some success. We depressed folks are often slaves to our inner-monologue voice, but I've found that forcing the same thoughts out loud turns down the volume on emotional triggers, allows me to be more objective, and helps keep me engaged with a task.
