Sorry Tryin, but I think he's looking for a more specific answer than "it's ok to talk to yourself.".
hippiechild,
I do what you describe above every night when I go to bed. I go over conversations I had that day or maybe the day before over and over,and sometimes I don't even sleep because of it. This is just a natural reaction to our social phobic life. We go over conversations because we think we could have said something better or something that made more sense or something more helpful, get my drift. The fact is, if everyone was programmed to say the perfect thing all of the time then this world would be boring as hell. Unfortunately, the only thing that's worked for me to get rid of these nightly thinking patterns is to take a double dose of clonazepam before bed. Benzodiazepines really do a good job of slowing your mind down in times of uncontrollable thoughts. I hope I helped...
Peace
