Unconcious conversations in my head

I thought this was the best place to post this. Because of severe trauma from age 2 at least to age 24, I was diagnosed and treated fairly successfully for PSTD. However, I am currently diagnosed with Bipolar unspecified, Generalized Anxiety w/Panic, Clinical Depression, and ADD all which began at age 12. To the point, forever, especially when anxious, I will be doing something meaningless like making a peanut butter sandwhich, and all of a sudden I will become AWARE of a dialogue taking place in my head but I can't make it out. It does not feel like these internal voices/thoughts/discussions belong to me, and it is always very disturbing. As soon as they "emerge" into conciousness, they disappear. I have looked everywhere on the web for this phenomenon, and all my doctors over the past 20 years just nod their heads without offering an explanation. Even when I ask, I don't get one. Has anyone else experienced this? It is very similar to my racing thoughts in that they come out of nowhere and are so fast I can't make sense of them but i feel those are my thoughts and not disconnected from me. Help please? I'm on an antipsychotic as a mood stabilizer and this hasn't happened in awhile, but my mixed moods are going up towards depression and anxiety lately.

I'm not a doctor, but I would like to say that they are your own thoughts, and the moment that you become aware of them is when they stop. With depersonalization, the mind is constantly thinking, and an awareness of these thoughts takes place. Try not to freak out when you hear it, and tune in. It's just you.

Thanks zSisyphus. I find that very comforting and a new way to look at things!
