I understand this too.....it's so hard to just leave and leave it there, like my T keeps telling me to do. She'll be like, take a deep breath, leave it here.....it'll be here when you come back. But it goes with me - always! The emotions, the memories and thoughts, words said/unsaid, the tears I couldn't cry.......but like melba, I've learned I will survive, hard as it is. I try deep breaths, and if it was really hard, sometimes I go get myself an ice cream cone and take a drive! This helps to drive away the feelings......I can just let them be and be with them and then they begin to feel manageable.
I also have this trick of making a sort of oasis in my mind, a calm space to go to even when there's a storm of emotions.....I focus on that and it helps.
