understanding very well and wanted to share with you a couple ways our system copes with hard t sessions when we cant immediately go home to sleep....
-having a "timed" (10 minutes) kind of de=briefing on paper to collect ourselves to go to next task
-a special tape we recorded to listen to walkman
-this may sound stupid.... but we have a kind of box (tupperware?) that we physically "put" the big feelings into until it's a safer/better time to address it
-some self care/self soothing with a special treat (for us it's usually ice cream for the lil ones or a special very expensive tea drink for the bigs)

I hope this helps a little and I'm sorry if I missed what you were asking.
Take gentle care of yourself
