Sounds like over all it was a good session for you.
I get those kind of voices and thoughts too. The way I counter them and stop them is by breaking the process down into steps -
1. I look around and notice things around me and touch something to remind myself to stay connected to the here and now instead of listening to the voices and thoughts.
2. I look around to see if there is anything or a situation going on that reminds me of those voices and thoughts.
2. If I find what it is that has triggered those voices and thoughts I then say - Ok there it is.
3. then I say to myself - ok Im ok, this is May 16, 2006.
4. I say - that voice and thought is a memory so it can not hurt me now.
5. I say That (situation or object that matches the voices and thoughts) is why I am hearing that thought or voice.
6. I say - I can listen to what it is and write it down so that later I can make a plan so that I will better next time
7. Or I can ... (fill in something from my emergency list of things to do when I am upset like writing, drawing taking a walk and paying attention to what I see, hear and so on while out walking ...ect)
8. Or I can write it down and do the emergency list of things too.
A visualization that helps me alot is closing my eyes and pretending I am sitting or laying out in the sun and the suns warmth warms and relaxes my body from head to toe.
My therapist has also recorded when we do relaxation visualizations in sessions and I listen and to those at home too by closing my eyes and pretending I am sitting in that therapy session doing that recorded relaxation visualization.
Hang in there.
