Yeah, I totally relate to the emotional hangover. It's a very real issue for me, one that can and often does interfere with my functioning in "real" life. I'm trying to be gentle with myself and recognize that I'm dealing with some pretty intense stuff, so the hangover is probably to be expected.

I've also started writing my T emails that say all the things that I'm thinking or that come up for me after a session, but then I send it to myself. I find that this is more effective for me than journaling because I have the sense of it "being heard" by sending it in email form. Usually a few days later things have settled down but there have been a few times when I have decided to send an edited version to my T via email. T has told me that the rare email is okay with him but not to make it a habit.

I also like the suggestion someone else had to plan to do more exercise afterwards. Sometimes that seems too much for me but I'm going to try it when I can.
