My T left me a voicemail the other day...we had an intense session the day before and she wanted me to know I was on her mind. I accidentally deleted it, but I had really wanted to save it...so got brave and left her a message asking if she would leave another message. So she did! I guess this is like the 'transitional objects' people have mentioned earlier in this thread?
Also - to combine both the blues/hangover threads I read through - it always takes me a while to process the session, so to speak. I go drive around a half hour, sometimes with music up loud, before going home so my husband doesn't see how undone or shell-shocked I look/feel sometimes. Sometimes it takes hours or days to get my head out of session; sometimes, I feel the need to mull things from the session over a lot...other times, I just feel happy about what transpired and go about with a sort of an after-therapy glow.
Usually, I journal my thoughts about things from the session....journaling helps clear my head from the things rattling around in it after session. If they're on paper, I'm free from obsessing about them!
